Subject: [PATCH v2 0/7] vfs: Use dlock list for SB's s_inodes list
Date: Mon, 11 Jul 2016 13:32:05 -0400 [thread overview]
Message-ID: <1468258332-61537-1-git-send-email-Waiman.Long@hpe.com> (raw)
v1->v2:
- Add a set of simple per-subnode APIs that is between percpu and
per-node in granularity.
- Make dlock list to use the per-subnode APIs so as to reduce the
total number of separate linked list that needs to be managed
and iterated.
- There is no change in patches 1-5.
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.
Patch 6 adds a new set of per-subnode APIs that allow distributed
resources with a granularity that is in between a per-cpu and per-node
systems.
Patch 7 modifies the dlock list to use the new per-subnode APIs so
that it will have less linked lists to manage and iterate compared
with the per-cpu version.
