Subject: [PATCH 0/5] vfs: Use dlock list for SB's s_inodes list

This is a follow up of the following patchset:

  [PATCH v7 0/4] vfs: Use per-cpu list for SB's s_inodes list
  https://lkml.org/lkml/2016/4/12/1009

The main change is the renaming of percpu list to dlock list, as
suggested by Christoph Lameter. It also adds a new patch from Boqun
Feng to add the __percpu modifier for parameters.

Patch 1 introduces the dlock list.

Patch 2 adds the __percpu modifier to the appropriate parameters.

Patch 3 cleans up the fsnotify_unmount_inodes() function by making
the code simpler and more standard.

Patch 4 replaces the use of list_for_each_entry_safe() in
evict_inodes() and invalidate_inodes() by list_for_each_entry().

Patch 5 modifies the superblock and inode structures to use the dlock
list. The corresponding functions that reference those structures
are modified.

Boqun Feng (1):
  lib/dlock-list: Add __percpu modifier for parameters

Jan Kara (2):
  fsnotify: Simplify inode iteration on umount
  vfs: Remove unnecessary list_for_each_entry_safe() variants

Waiman Long (2):
  lib/dlock-list: Distributed and lock-protected lists
  vfs: Use dlock list for superblock's inode list
