[PATCH] signal: trace_signal_deliver when signal_group_exit

by Zhenliang Wei

In the following commit, removing SIGKILL from each thread signal mask and executing "goto fatal" directly will skip the call to "trace_signal_deliver". At this point, the delivery tracking of the SIGKILL signal will be inaccurate. commit cf43a757fd4944 ("signal: Restore the stop PTRACE_EVENT_EXIT") Therefore, we need to add trace_signal_deliver before "goto fatal" after executing sigdelset.

[PATCH v2] clk: hi3660: Mark clk_gate_ufs_subsys as critical

by Leo Yan

clk_gate_ufs_subsys is a system bus clock, turning off it will introduce lockup issue during system suspend flow. Let's mark clk_gate_ufs_subsys as critical clock, thus keeps it on during system suspend and resume.

[PATCH] libnvdimm/namespace: Fix label tracking error

by Dan Williams

Users have reported intermittent occurrences of DIMM initialization failures due to duplicate allocations of address capacity detected in the labels, or errors of the form below, both have the same root cause. nd namespace1.4: failed to track label: 0 WARNING: CPU: 17 PID: 1381 at drivers/nvdimm/label.c:863 RIP: 0010:__pmem_label_update+0x56c/0x590 [libnvdimm] Call Trace: ? nd_pmem_namespace_label_update+0xd6/0x160 [libnvdimm] nd_pmem_namespace_label_update+0xd6/0x160 [libnvdimm] uuid_store+0x17e/0x190 [libnvdimm] kernfs_fop_write+0xf0/0x1a0 vfs_write+0xb7/0x1b0 ksys_write+0x57/0xd0 do_syscall_64+0x60/0x210 Unfortunately those reports were typically with a busy parallel namespace creation / destruction loop making it difficult to see the components of the bug. However, Jane provided a simple reproducer using the work-in-progress sub-section implementation. When ndctl is reconfiguring a namespace it may take an existing defunct / disabled namespace and reconfigure it with a new uuid and other parameters. Critically namespace_update_uuid() takes existing address resources and renames them for the new namespace to use / reconfigure as it sees fit. The bug is that this rename only happens in the resource tracking tree.

[withdrawn] libnvdimm-pfn-fix-fsdax-mode-namespace-info-block-zero-fields.patch removed from -mm tree

by akpm＠linux-foundation.org

The patch titled Subject: libnvdimm/pfn: fix fsdax-mode namespace info-block zero-fields has been removed from the -mm tree. Its filename was libnvdimm-pfn-fix-fsdax-mode-namespace-info-block-zero-fields.patch This patch was dropped because it was withdrawn ------------------------------------------------------ From: Dan Williams <dan.j.williams(a)intel.com> Subject: libnvdimm/pfn: fix fsdax-mode namespace info-block zero-fields At namespace creation time there is the potential for the "expected to be zero" fields of a 'pfn' info-block to be filled with indeterminate data. While the kernel buffer is zeroed on allocation it is immediately overwritten by nd_pfn_validate() filling it with the current contents of the on-media info-block location. For fields like, 'flags' and the 'padding' it potentially means that future implementations can not rely on those fields being zero. In preparation to stop using the 'start_pad' and 'end_trunc' fields for section alignment, arrange for fields that are not explicitly initialized to be guaranteed zero. Bump the minor version to indicate it is safe to assume the 'padding' and 'flags' are zero. Otherwise, this corruption is expected to benign since all other critical fields are explicitly initialized. -stable note: It's not a problem unless a kernel implementation is explicitly expecting those fields to be zero-initialized. I only marked it for -stable in case some future kernel backports patch12. Otherwise it's benign on older kernels that don't have patch12 since all fields are indeed initialized.

The patch titled Subject: mm: do not boost watermarks to avoid fragmentation for the DISCONTIG memory model has been added to the -mm tree. Its filename is mm-do-not-boost-watermarks-to-avoid-fragmentation-for-the-discontig-memory-model.patch This patch should soon appear at http://ozlabs.org/~akpm/mmots/broken-out/mm-do-not-boost-watermarks-to-avoi… and later at http://ozlabs.org/~akpm/mmotm/broken-out/mm-do-not-boost-watermarks-to-avoi… Before you just go and hit "reply", please: a) Consider who else should be cc'ed b) Prefer to cc a suitable mailing list as well c) Ideally: find the original patch on the mailing list and do a reply-to-all to that, adding suitable additional cc's *** Remember to use Documentation/process/submit-checklist.rst when testing your code *** The -mm tree is included into linux-next and is updated there every 3-4 working days ------------------------------------------------------ From: Mel Gorman <mgorman(a)techsingularity.net> Subject: mm: do not boost watermarks to avoid fragmentation for the DISCONTIG memory model Mikulas Patocka reported that 1c30844d2dfe ("mm: reclaim small amounts of memory when an external fragmentation event occurs") "broke" memory management on parisc. The machine is not NUMA but the DISCONTIG model creates three pgdats even though it's a UMA machine for the following ranges 0) Start 0x0000000000000000 End 0x000000003fffffff Size 1024 MB 1) Start 0x0000000100000000 End 0x00000001bfdfffff Size 3070 MB 2) Start 0x0000004040000000 End 0x00000040ffffffff Size 3072 MB Mikulas reported: With the patch 1c30844d2, the kernel will incorrectly reclaim the first zone when it fills up, ignoring the fact that there are two completely free zones. Basiscally, it limits cache size to 1GiB. For example, if I run: # dd if=/dev/sda of=/dev/null bs=1M count=2048 - with the proper kernel, there should be "Buffers - 2GiB" when this command finishes. With the patch 1c30844d2, buffers will consume just 1GiB or slightly more, because the kernel was incorrectly reclaiming them. The page allocator and reclaim makes assumptions that pgdats really represent NUMA nodes and zones represent ranges and makes decisions on that basis. Watermark boosting for small pgdats leads to unexpected results even though this would have behaved reasonably on SPARSEMEM. DISCONTIG is essentially deprecated and even parisc plans to move to SPARSEMEM so there is no need to be fancy, this patch simply disables watermark boosting by default on DISCONTIGMEM.
