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

[Waiman Long]

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.
