Subject[PATCH 00/34] vfs: atomic open v3
Date
This series allows clean implementation of atomic lookup+(create)+open
operations that previously were done via ->lookup and ->create using open
intents.

Changes from the last version:

- fixed some bugs
- pulled the EOPENSTALE patches towards the head of the queue
- split up some patches for easier reviewability

git tree is here:

git://git.kernel.org/pub/scm/linux/kernel/git/mszeredi/vfs.git atomic-open.v3

Thanks,
Miklos
