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.
