Subject: [RFC PATCH 0/3] lib/list_batch: A simple list insertion/deletion batching facility

This patchset introduces a simple list insertion/deletion batching
facility to batch multiple list insertion and deletion operations
into a single one under one lock/unlock critical section.

Patch 1 introduces this new facility.

Patch 2 enables it for the x86-64 architecture.

Patch 3 makes the insertion and deletion of the VFS superblock's
inode list to use the new list batching functions.

Waiman Long (3):
  lib/list_batch: A simple list insertion/deletion batching facility
  lib/list_batch, x86: Enable list insertion/deletion batching in
    x86-64
  vfs: Enable list batching for the superblock's inode list
