memcg: flush lruvec stats in the refault
Shakeel Butt: Prior to the commit 7e1c0d6f5820 ("memcg: switch lruvec stats to rstat") and the commit aa48e47e3906 ("memcg: infrastructure to flush memcg stats"), each lruvec memcg stats can be off by (nr_cgroups * nr_cpus * 32) at worst and for unbounded amount of time.

drm/nouveau/nvkm: Replace -ENOSYS with -ENODEV
Guenter Roeck: nvkm test builds fail with the following error. drivers/gpu/drm/nouveau/nvkm/engine/device/ctrl.c: In function 'nvkm_control_mthd_pstate_info': drivers/gpu/drm/nouveau/nvkm/engine/device/ctrl.c:60:35: error: overflow in conversion from 'int' to '__s8' {aka 'signed char'} changes value from '-251' to '5' The code builds on most architectures, but fails on parisc where ENOSYS is defined as 251. Replace the error code with -ENODEV (-19).

net: 6pack: Fix tx timeout and slot time
Guenter Roeck: tx timeout and slot time are currently specified in units of HZ.

3com 3c515: make it compile on 64-bit architectures
Linus Torvalds: This driver isn't enabled most places because of the ISA config dependency, but alpha still has it.

qnx4: avoid stringop-overread errors
Linus Torvalds: The qnx4 directory entries are 64-byte blocks that have different contents depending on the a status byte that is in the last byte of the block.

tools: compiler-gcc.h: Guard error attribute use with __has_attribute
Nathan Chancellor: When building objtool with HOSTCC=clang, there are several errors along the lines of orc_dump.c:201:28: error: unknown attribute 'error' ignored [-Werror,-Wunknown-attributes] This occurs after commit 4e59869aa655 ("compiler-gcc.h: drop checks for older GCC versions"), which removed the GCC_VERSION gating.

Enable '-Werror' by default for all kernel builds
Linus Torvalds

d_path: make 'prepend()' fill up the buffer exactly on overflow
Linus Torvalds: Instead of just marking the buffer as having overflowed, fill it up as much as we can.

Most Popular This Year

mailmap: add two more addresses of Uwe Kleine-König
Uwe Kleine-König: This fixes attribution for the commits (among others)

mm: add Kernel Electric-Fence infrastructure
Alexander Potapenko: Patch series "KFENCE: A low-overhead sampling-based memory safety error detector", v7. This adds the Kernel Electric-Fence (KFENCE) infrastructure.

MIPS: make userspace mapping young by default
Huang Pei: MIPS page fault path(except huge page) takes 3 exceptions (1 TLB Miss + 2 TLB Invalid), butthe second TLB Invalid exception is just triggered by __update_tlb from do_page_fault writing tlb without _PAGE_VALID set.

mm: generalise COW SMC TLB flushing race comment
Nicholas Piggin: I'm not sure if I'm completely missing something here, but AFAIKS the reference to the mysterious "COW SMC race" confuses the issue.

checkpatch: enable GIT_DIR environment use to set git repository location
Joe Perches: If set, use the environment variable GIT_DIR to change the default .git location of the kernel git tree.

arm64: make _TIF_WORK_MASK bits contiguous
Mark Rutland: We need the bits of _TIF_WORK_MASK to be contiguous in order to to use this as an immediate argument to an AND instruction in entry.S.

mm: list_lru: set shrinker map bit when child nr_items is not zero
Yang Shi: When investigating a slab cache bloat problem, significant amount of negative dentry cache was seen, but confusingly they neither got shrunk by reclaimer (the host has very tight memory) nor be shrunk by dropping cache.

proc mountinfo: make splice available again
Linus Torvalds: Since commit 36e2c7421f02 ("fs: don't allow splice read/write without explicit ops") we've required that file operation structures explicitly enable splice support, rather than falling back to the default handlers.

mm: make pagecache tagged lookups return only head pages
Matthew Wilcox (Oracle): Patch series "Overhaul multi-page lookups for THP", v4. This THP prep patchset changes several page cache iteration APIs to only return head pages. - It's only possible to tag head pages in the page cache, so only return head pages, not all their subpages.- Factor a lot of common code out of the various batch lookup routines- Add mapping_seek_hole_data()- Unify find_get_entries() and pagevec_lookup_entries() - Make find_get_entries only return head pages, like find_get_entry(). These are only loosely connected, but they seem to make sense together as a series. This patch (of 14): Pagecache tags are used for dirty page writeback.

mm: cma: allocate cma areas bottom-up
Roman Gushchin: Currently cma areas without a fixed base are allocated close to the end of the node.
