      mm/vmstat.c: fix /proc/vmstat format for CONFIG_DEBUG_TLBFLUSH=y CONFIG_SMP=n · e8277b3b
      Konstantin Khlebnikov 提交于
      Commit 58bc4c34 ("mm/vmstat.c: skip NR_TLB_REMOTE_FLUSH* properly")
      depends on skipping vmstat entries with empty name introduced in
      7aaf7727 ("mm: don't show nr_indirectly_reclaimable in
      /proc/vmstat") but reverted in b29940c1 ("mm: rename and change
      semantics of nr_indirectly_reclaimable_bytes").
      
      So skipping no longer works and /proc/vmstat has misformatted lines " 0".
      
      This patch simply shows debug counters "nr_tlb_remote_*" for UP.

      mm/memory_hotplug: do not unlock after failing to take the device_hotplug_lock · 37803841
      zhong jiang 提交于
      When adding memory by probing a memory block in the sysfs interface,
      there is an obvious issue where we will unlock the device_hotplug_lock
      when we failed to takes it.
      
      That issue was introduced in 8df1d0e4 ("mm/memory_hotplug: make
      add_memory() take the device_hotplug_lock").
      
      We should drop out in time when failing to take the device_hotplug_lock.

      mm: swapoff: shmem_unuse() stop eviction without igrab() · af53d3e9
      Hugh Dickins 提交于
      The igrab() in shmem_unuse() looks good, but we forgot that it gives no
      protection against concurrent unmounting: a point made by Konstantin
      Khlebnikov eight years ago, and then fixed in 2.6.39 by 778dd893
      ("tmpfs: fix race between umount and swapoff").  The current 5.1-rc
      swapoff is liable to hit "VFS: Busy inodes after unmount of tmpfs.
      Self-destruct in 5 seconds.  Have a nice day..." followed by GPF.
      
      Once again, give up on using igrab(); but don't go back to making such
      heavy-handed use of shmem_swaplist_mutex as last time: that would spoil
      the new design, and I expect could deadlock inside shmem_swapin_page().
      
      Instead, shmem_unuse() just raise a "stop_eviction" count in the shmem-
      specific inode, and shmem_evict_inode() wait for that to go down to 0.
      Call it "stop_eviction" rather than "swapoff_busy" because it can be put
      to use for others later (huge tmpfs patches expect to use it).
      
      That simplifies shmem_unuse(), protecting it from both unlink and
      unmount; and in practice lets it locate all the swap in its first try.
      But do not rely on that: there's still a theoretical case, when
      shmem_writepage() might have been preempted after its get_swap_page(),
      before making the swap entry visible to swapoff.

      mm: swapoff: take notice of completion sooner · 64165b1a
      Hugh Dickins 提交于
      The old try_to_unuse() implementation was driven by find_next_to_unuse(),
      which terminated as soon as all the swap had been freed.
      
      Add inuse_pages checks now (alongside signal_pending()) to stop scanning
      mms and swap_map once finished.
      
      The same ought to be done in shmem_unuse() too, but never was before,
      and needs a different interface: so leave it as is for now.

      mm: swapoff: remove too limiting SWAP_UNUSE_MAX_TRIES · dd862deb
      Hugh Dickins 提交于
      SWAP_UNUSE_MAX_TRIES 3 appeared to work well in earlier testing, but
      further testing has proved it to be a source of unnecessary swapoff
      EBUSY failures (which can then be followed by unmount EBUSY failures).
      
      When mmget_not_zero() or shmem's igrab() fails, there is an mm exiting
      or inode being evicted, freeing up swap independent of try_to_unuse().
      Those typically completed much sooner than the old quadratic swapoff,
      but now it's more common that swapoff may need to wait for them.
      
      It's possible to move those cases from init_mm.mmlist and shmem_swaplist
      to separate "exiting" swaplists, and try_to_unuse() then wait for those
      lists to be emptied; but we've not bothered with that in the past, and
      don't want to risk missing some other forgotten case.  So just revert to
      cycling around until the swap is gone, without any retries limit.

      mm: swapoff: shmem_find_swap_entries() filter out other types · 87039546
      Hugh Dickins 提交于
      Swapfile "type" was passed all the way down to shmem_unuse_inode(), but
      then forgotten from shmem_find_swap_entries(): with the result that
      removing one swapfile would try to free up all the swap from shmem - no
      problem when only one swapfile anyway, but counter-productive when more,
      causing swapoff to be unnecessarily OOM-killed when it should succeed.

      slab: store tagged freelist for off-slab slabmgmt · 1a62b18d
      Qian Cai 提交于
      Commit 51dedad0 ("kasan, slab: make freelist stored without tags")
      calls kasan_reset_tag() for off-slab slab management object leading to
      freelist being stored non-tagged.
      
      However, cache_grow_begin() calls alloc_slabmgmt() which calls
      kmem_cache_alloc_node() assigns a tag for the address and stores it in
      the shadow address.  As the result, it causes endless errors below
      during boot due to drain_freelist() -> slab_destroy() ->
      kasan_slab_free() which compares already untagged freelist against the
      stored tag in the shadow address.
      
      Since off-slab slab management object freelist is such a special case,
      just store it tagged.  Non-off-slab management object freelist is still
      stored untagged which has not been assigned a tag and should not cause
      any other troubles with this inconsistency.

      signal: use fdget() since we don't allow O_PATH · 738a7832
      Christian Brauner 提交于
      As stated in the original commit for pidfd_send_signal() we don't allow
      to signal processes through O_PATH file descriptors since it is
      semantically equivalent to a write on the pidfd.
      
      We already correctly error out right now and return EBADF if an O_PATH
      fd is passed.  This is because we use file->f_op to detect whether a
      pidfd is passed and O_PATH fds have their file->f_op set to empty_fops
      in do_dentry_open() and thus fail the test.
      
      Thus, there is no regression.  It's just semantically correct to use
      fdget() and return an error right from there instead of taking a
      reference and returning an error later.
