[PATCH v2 1/9] btrfs: fix the incorrect @max_bytes value for find_lock_delalloc_range()

by Qu Wenruo

[BUG] With my local branch to enable bs > ps support for btrfs, sometimes I hit the following ASSERT() inside submit_one_sector(): ASSERT(block_start != EXTENT_MAP_HOLE); Please note that it's not yet possible to hit this ASSERT() in the wild yet, as it requires btrfs bs > ps support, which is not even in the development branch. But on the other hand, there is also a very low chance to hit above ASSERT() with bs < ps cases, so this is an existing bug affect not only the incoming bs > ps support but also the existing bs < ps support. [CAUSE] Firstly that ASSERT() means we're trying to submit a dirty block but without a real extent map nor ordered extent map backing it. Furthermore with extra debugging, the folio triggering such ASSERT() is always larger than the fs block size in my bs > ps case. (8K block size, 4K page size) After some more debugging, the ASSERT() is trigger by the following sequence: extent_writepage() | We got a 32K folio (4 fs blocks) at file offset 0, and the fs block | size is 8K, page size is 4K. | And there is another 8K folio at file offset 32K, which is also | dirty. | So the filemap layout looks like the following: | | "||" is the filio boundary in the filemap. | "//| is the dirty range. | | 0 8K 16K 24K 32K 40K | |////////| |//////////////////////||////////| | |- writepage_delalloc() | |- find_lock_delalloc_range() for [0, 8K) | | Now range [0, 8K) is properly locked. | | | |- find_lock_delalloc_range() for [16K, 40K) | | |- btrfs_find_delalloc_range() returned range [0, 8K) | | |- lock_delalloc_folios() succeeded. | | | | | | The filemap range [32K, 40K) got dropped from filemap. | | | | | |- lock_delalloc_folios() failed with -EAGAIN. | | | As it failed to lock the folio at [32K, 40K). | | | | | |- loops = 1; | | |- max_bytes = PAGE_SIZE; | | |- goto again; | | | This will re-do the lookup for dirty delalloc ranges. | | | | | |- btrfs_find_delalloc_range() called with @max_bytes == 4K | | | This is smaller than block size, so | | | btrfs_find_delalloc_range() is unable to return any range. | | \- return false; | | | \- Now only range [0, 8K) has an OE for it, but for dirty range | [16K, 32K) it's dirty without an OE. | This breaks the assumption that writepage_delalloc() will find | and lock all dirty ranges inside the folio. | |- extent_writepage_io() |- submit_one_sector() for [0, 8K) | Succeeded | |- submit_one_sector() for [16K, 24K) Triggering the ASSERT(), as there is no OE, and the original extent map is a hole. Please note that, this also exposed the same problem for bs < ps support. E.g. with 64K page size and 4K block size. If we failed to lock a folio, and falls back into the "loops = 1;" branch, we will re-do the search using 64K as max_bytes. Which may fail again to lock the next folio, and exit early without handling all dirty blocks inside the folio. [FIX] Instead of using the fixed size PAGE_SIZE as @max_bytes, use @sectorsize, so that we are ensured to find and lock any remaining blocks inside the folio. And since we're here, add an extra ASSERT() to before calling btrfs_find_delalloc_range() to make sure the @max_bytes is at least no smaller than a block to avoid false negative.

[merged mm-stable] mm-damon-lru_sort-use-param_ctx-for-damon_attrs-staging.patch removed from -mm tree

by Andrew Morton

The quilt patch titled Subject: mm/damon/lru_sort: use param_ctx for damon_attrs staging has been removed from the -mm tree. Its filename was mm-damon-lru_sort-use-param_ctx-for-damon_attrs-staging.patch This patch was dropped because it was merged into the mm-stable branch of git://git.kernel.org/pub/scm/linux/kernel/git/akpm/mm ------------------------------------------------------ From: SeongJae Park <sj(a)kernel.org> Subject: mm/damon/lru_sort: use param_ctx for damon_attrs staging Date: Mon, 15 Sep 2025 20:15:49 -0700 damon_lru_sort_apply_parameters() allocates a new DAMON context, stages user-specified DAMON parameters on it, and commits to running DAMON context at once, using damon_commit_ctx(). The code is, however, directly updating the monitoring attributes of the running context. And the attributes are over-written by later damon_commit_ctx() call. This means that the monitoring attributes parameters are not really working. Fix the wrong use of the parameter context.

[PATCH] rtc: pcf2127: fix SPI command byte for PCF2131 backport

by Bruno Thomsen

When commit fa78e9b606a472495ef5b6b3d8b45c37f7727f9d upstream was backported to LTS branches linux-6.12.y and linux-6.6.y, the SPI regmap config fix got applied to the I2C regmap config. Most likely due to a new RTC get/set parm feature introduced in 6.14 causing regmap config sections in the buttom of the driver to move. LTS branch linux-6.1.y and earlier does not have PCF2131 device support. Issue can be seen in buttom of this diff in stable/linux.git tree: git diff master..linux-6.12.y -- drivers/rtc/rtc-pcf2127.c Fixes: ee61aec8529e ("rtc: pcf2127: fix SPI command byte for PCF2131") Fixes: 5cdd1f73401d ("rtc: pcf2127: fix SPI command byte for PCF2131") Cc: stable(a)vger.kernel.org Cc: Alexandre Belloni <alexandre.belloni(a)bootlin.com> Cc: Elena Popa <elena.popa(a)nxp.com> Cc: Hugo Villeneuve <hvilleneuve(a)dimonoff.com> Signed-off-by: Bruno Thomsen <bruno.thomsen(a)gmail.com> --- drivers/rtc/rtc-pcf2127.c | 10 +++++----- 1 file changed, 5 insertions(+), 5 deletions(-) diff --git a/drivers/rtc/rtc-pcf2127.c b/drivers/rtc/rtc-pcf2127.c index fc079b9dcf71..502571f0c203 100644 --- a/drivers/rtc/rtc-pcf2127.c +++ b/drivers/rtc/rtc-pcf2127.c @@ -1383,11 +1383,6 @@ static int pcf2127_i2c_probe(struct i2c_client *client) variant = &pcf21xx_cfg[type]; } - if (variant->type == PCF2131) { - config.read_flag_mask = 0x0; - config.write_flag_mask = 0x0; - } - config.max_register = variant->max_register, regmap = devm_regmap_init(&client->dev, &pcf2127_i2c_regmap, @@ -1461,6 +1456,11 @@ static int pcf2127_spi_probe(struct spi_device *spi) variant = &pcf21xx_cfg[type]; } + if (variant->type == PCF2131) { + config.read_flag_mask = 0x0; + config.write_flag_mask = 0x0; + } + config.max_register = variant->max_register; regmap = devm_regmap_init_spi(spi, &config); base-commit: 880e4ff5d6c8dc6b660f163a0e9b68b898cc6310 -- 2.50.1

[PATCH 0/7 5.10.y] Cherry pick of minmax.h commits from 5.15.y

by Eliav Farber

This series backports seven commits from v5.15.y that update minmax.h and related code: - ed6e37e30826 ("tracing: Define the is_signed_type() macro once") - 998f03984e25 ("minmax: sanity check constant bounds when clamping") - d470787b25e6 ("minmax: clamp more efficiently by avoiding extra comparison") - 1c2ee5bc9f11 ("minmax: fix header inclusions") - d53b5d862acd ("minmax: allow min()/max()/clamp() if the arguments have the same signedness.") - 7ed91c5560df ("minmax: allow comparisons of 'int' against 'unsigned char/short'") - 22f7794ef5a3 ("minmax: relax check to allow comparison between unsigned arguments and signed constants") The main motivation is commit d53b5d862acd, which removes the strict type check in min()/max() when both arguments have the same signedness. Without this, kernel 5.10 builds can emit warnings that become build failures when -Werror is used. Additionally, commit ed6e37e30826 from tracing is required as a dependency; without it, compilation fails. Andy Shevchenko (1): minmax: fix header inclusions Bart Van Assche (1): tracing: Define the is_signed_type() macro once David Laight (3): minmax: allow min()/max()/clamp() if the arguments have the same signedness. minmax: allow comparisons of 'int' against 'unsigned char/short' minmax: relax check to allow comparison between unsigned arguments and signed constants Jason A.

Possible dependencies: thanks, greg k-h ------------------ original commit in Linus's tree ------------------ From 1e56310b40fd2e7e0b9493da9ff488af145bdd0c Mon Sep 17 00:00:00 2001 From: Vasant Hegde <vasant.hegde(a)amd.com> Date: Sat, 13 Sep 2025 06:26:57 +0000 Subject: [PATCH] iommu/amd/pgtbl: Fix possible race while increase page table level The AMD IOMMU host page table implementation supports dynamic page table levels (up to 6 levels), starting with a 3-level configuration that expands based on IOVA address. The kernel maintains a root pointer and current page table level to enable proper page table walks in alloc_pte()/fetch_pte() operations. The IOMMU IOVA allocator initially starts with 32-bit address and onces its exhuasted it switches to 64-bit address (max address is determined based on IOMMU and device DMA capability). To support larger IOVA, AMD IOMMU driver increases page table level. But in unmap path (iommu_v1_unmap_pages()), fetch_pte() reads pgtable->[root/mode] without lock. So its possible that in exteme corner case, when increase_address_space() is updating pgtable->[root/mode], fetch_pte() reads wrong page table level (pgtable->mode). It does compare the value with level encoded in page table and returns NULL. This will result is iommu_unmap ops to fail and upper layer may retry/log WARN_ON. CPU 0 CPU 1 ------ ------ map pages unmap pages alloc_pte() -> increase_address_space() iommu_v1_unmap_pages() -> fetch_pte() pgtable->root = pte (new root value) READ pgtable->[mode/root] Reads new root, old mode Updates mode (pgtable->mode += 1) Since Page table level updates are infrequent and already synchronized with a spinlock, implement seqcount to enable lock-free read operations on the read path.

Series of lru_add_drain_all()-related patches, arising from recent mm/gup migration report from Will Deacon. This patch (of 5): Will Deacon reports:- When taking a longterm GUP pin via pin_user_pages(), __gup_longterm_locked() tries to migrate target folios that should not be longterm pinned, for example because they reside in a CMA region or movable zone. This is done by first pinning all of the target folios anyway, collecting all of the longterm-unpinnable target folios into a list, dropping the pins that were just taken and finally handing the list off to migrate_pages() for the actual migration. It is critically important that no unexpected references are held on the folios being migrated, otherwise the migration will fail and pin_user_pages() will return -ENOMEM to its caller. Unfortunately, it is relatively easy to observe migration failures when running pKVM (which uses pin_user_pages() on crosvm's virtual address space to resolve stage-2 page faults from the guest) on a 6.15-based Pixel 6 device and this results in the VM terminating prematurely. In the failure case, 'crosvm' has called mlock(MLOCK_ONFAULT) on its mapping of guest memory prior to the pinning. Subsequently, when pin_user_pages() walks the page-table, the relevant 'pte' is not present and so the faulting logic allocates a new folio, mlocks it with mlock_folio() and maps it in the page-table. Since commit 2fbb0c10d1e8 ("mm/munlock: mlock_page() munlock_page() batch by pagevec"), mlock/munlock operations on a folio (formerly page), are deferred. For example, mlock_folio() takes an additional reference on the target folio before placing it into a per-cpu 'folio_batch' for later processing by mlock_folio_batch(), which drops the refcount once the operation is complete. Processing of the batches is coupled with the LRU batch logic and can be forcefully drained with lru_add_drain_all() but as long as a folio remains unprocessed on the batch, its refcount will be elevated. This deferred batching therefore interacts poorly with the pKVM pinning scenario as we can find ourselves in a situation where the migration code fails to migrate a folio due to the elevated refcount from the pending mlock operation. Hugh Dickins adds:- !folio_test_lru() has never been a very reliable way to tell if an lru_add_drain_all() is worth calling, to remove LRU cache references to make the folio migratable: the LRU flag may be set even while the folio is held with an extra reference in a per-CPU LRU cache. 5.18 commit 2fbb0c10d1e8 may have made it more unreliable. Then 6.11 commit 33dfe9204f29 ("mm/gup: clear the LRU flag of a page before adding to LRU batch") tried to make it reliable, by moving LRU flag clearing; but missed the mlock/munlock batches, so still unreliable as reported. And it turns out to be difficult to extend 33dfe9204f29's LRU flag clearing to the mlock/munlock batches: if they do benefit from batching, mlock/munlock cannot be so effective when easily suppressed while !LRU. Instead, switch to an expected ref_count check, which was more reliable all along: some more false positives (unhelpful drains) than before, and never a guarantee that the folio will prove migratable, but better. Note on PG_private_2: ceph and nfs are still using the deprecated PG_private_2 flag, with the aid of netfs and filemap support functions. Although it is consistently matched by an increment of folio ref_count, folio_expected_ref_count() intentionally does not recognize it, and ceph folio migration currently depends on that for PG_private_2 folios to be rejected. New references to the deprecated flag are discouraged, so do not add it into the collect_longterm_unpinnable_folios() calculation: but longterm pinning of transiently PG_private_2 ceph and nfs folios (an uncommon case) may invoke a redundant lru_add_drain_all(). And this makes easy the backport to earlier releases: up to and including 6.12, btrfs also used PG_private_2, but without a ref_count increment. Note for stable backports: requires 6.16 commit 86ebd50224c0 ("mm: add folio_expected_ref_count() for reference count calculation").
