Subject: [RFC PATCH 0/2] vfs: Use per-cpu list for SB's s_inodes list
Date: Tue, 16 Feb 2016 20:31:18 -0500 [thread overview]
Message-ID: <1455672680-7153-1-git-send-email-Waiman.Long@hpe.com> (raw)
This patch is a replacement of my previous list batching patch -
https://lwn.net/Articles/674105/. Compared with the previous patch,
this one provides better performance and fairness. However, it also
requires a bit more changes in the VFS layer.
This patchset is a derivative of Andi Kleen's patch on "Initial per
cpu list for the per sb inode list"
https://git.kernel.org/cgit/linux/kernel/git/ak/linux-misc.git/commit/?h=hle315/combined&id=f1cf9e715a40f44086662ae3b29f123cf059cbf4
Patch 1 introduces the per-cpu list.
Patch 2 modifies the superblock and inode structures to use the per-cpu
list. The corresponding functions that reference those structures are
modified.

lib/percpu-list: Per-cpu list with associated per-cpu locks
