[PATCH 00/21] vfs: atomic open v6 (part 2)

[Miklos Szeredi]

This is part 2 of the atomic open series.  It introduces i_op->atomic_open() and
converts filesystems that abuse ->lookup() and ->create() to use this new
interface instead.

This version has one bugfix and several cleanups, reported by David Howells.
Also updated documentation in Documentation/filesytems/{vfs.txt,Locking}.

Al, please apply.

Thanks,
Miklos
