[merged mm-hotfixes-stable] mm-multi-gen-lru-remove-mm_leaf_old-and-mm_nonleaf_total-stats.patch removed from -mm tree

by Andrew Morton

The quilt patch titled Subject: mm: multi-gen LRU: remove MM_LEAF_OLD and MM_NONLEAF_TOTAL stats has been removed from the -mm tree. Its filename was mm-multi-gen-lru-remove-mm_leaf_old-and-mm_nonleaf_total-stats.patch This patch was dropped because it was merged into the mm-hotfixes-stable branch of git://git.kernel.org/pub/scm/linux/kernel/git/akpm/mm ------------------------------------------------------ From: Yu Zhao <yuzhao(a)google.com> Subject: mm: multi-gen LRU: remove MM_LEAF_OLD and MM_NONLEAF_TOTAL stats Date: Sat, 19 Oct 2024 01:29:38 +0000 Patch series "mm: multi-gen LRU: Have secondary MMUs participate in MM_WALK". Today, the MM_WALK capability causes MGLRU to clear the young bit from PMDs and PTEs during the page table walk before eviction, but MGLRU does not call the clear_young() MMU notifier in this case. By not calling this notifier, the MM walk takes less time/CPU, but it causes pages that are accessed mostly through KVM / secondary MMUs to appear younger than they should be. We do call the clear_young() notifier today, but only when attempting to evict the page, so we end up clearing young/accessed information less frequently for secondary MMUs than for mm PTEs, and therefore they appear younger and are less likely to be evicted. Therefore, memory that is *not* being accessed mostly by KVM will be evicted *more* frequently, worsening performance. ChromeOS observed a tab-open latency regression when enabling MGLRU with a setup that involved running a VM: Tab-open latency histogram (ms) Version p50 mean p95 p99 max base 1315 1198 2347 3454 10319 mglru 2559 1311 7399 12060 43758 fix 1119 926 2470 4211 6947 This series replaces the final non-selftest patchs from this series[1], which introduced a similar change (and a new MMU notifier) with KVM optimizations. I'll send a separate series (to Sean and Paolo) for the KVM optimizations. This series also makes proactive reclaim with MGLRU possible for KVM memory. I have verified that this functions correctly with the selftest from [1], but given that that test is a KVM selftest, I'll send it with the rest of the KVM optimizations later. Andrew, let me know if you'd like to take the test now anyway. [1]: https://lore.kernel.org/linux-mm/20240926013506.860253-18-jthoughton@google… This patch (of 2): The removed stats, MM_LEAF_OLD and MM_NONLEAF_TOTAL, are not very helpful and become more complicated to properly compute when adding test/clear_young() notifiers in MGLRU's mm walk.

Backport smb client char/block fixes

Hello, I would like to propose backporting these two commits into stable: * 663f295e3559 ("smb: client: fix parsing of device numbers") * a9de67336a4a ("smb: client: set correct device number on nfs reparse points") Linux SMB client without these two recent fixes swaps device major and minor numbers, which makes basically char/block device nodes unusable. Commit 663f295e3559 ("smb: client: fix parsing of device numbers") should have had following Fixes line: Fixes: 45e724022e27 ("smb: client: set correct file type from NFS reparse points") And commit a9de67336a4a ("smb: client: set correct device number on nfs reparse points") should have contained line: Fixes: 102466f303ff ("smb: client: allow creating special files via reparse points") Pali

[PATCH v2] lib: string_helpers: silence snprintf() output truncation warning

From: Bartosz Golaszewski <bartosz.golaszewski(a)linaro.org> The output of ".%03u" with the unsigned int in range [0, 4294966295] may get truncated if the target buffer is not 12 bytes. This can't really happen here as the 'remainder' variable cannot exceed 999 but the compiler doesn't know it. To make it happy just increase the buffer to where the warning goes away.

[PATCH iwl-net v2 1/2] idpf: avoid vport access in idpf_get_link_ksettings

by Pavan Kumar Linga

When the device control plane is removed or the platform running device control plane is rebooted, a reset is detected on the driver. On driver reset, it releases the resources and waits for the reset to complete. If the reset fails, it takes the error path and releases the vport lock. At this time if the monitoring tools tries to access link settings, it call traces for accessing released vport pointer. To avoid it, move link_speed_mbps to netdev_priv structure which removes the dependency on vport pointer and the vport lock in idpf_get_link_ksettings. Also use netif_carrier_ok() to check the link status and adjust the offsetof to use link_up instead of link_speed_mbps.
