Subject: [PATCH 00/25] vfs: atomic open RFC
This series allows clean implementation of atomic lookup+(create)+open and
create+open operations that previously were done via ->lookup and ->create using
open intents.
Testing and review is welcome, but at this stage mainly I'd like to hear
opinions on the overall design of the new interfaces.
This is based on the vfs fixes patchset posted previously on -fsdevel.
git tree is here:
git://git.kernel.org/pub/scm/linux/kernel/git/mszeredi/vfs.git atomic-open
Thanks,
Miklos
