As discussed at KS I've collected up the VFS patches from 3 month worth
of linux-fsdevel archives.
The major changes are lseek locking and O_DIRECT cache footprint
optimizations from Andi Kleen, which Al already had queued up in his
non-public queue before he caught the flu. In addition to that
it's just fairly small patches. If I missed anything important please
send it my way until Al is back.
There is a few promiment things intentionally missing:
- ->d_prune support from Sage. I though we finally had this one nailed
down a few weeks ago, but it crashes btrfs when running xfstests, so
we'll need another round.
- Miklos' remount r/o fixes. I really wanted them, but found a few
minor issue and want to give them more QA first. Hopefully we can
get them in during a second pull for 3.2, even more hopefull Al will
be back in time as he hasn't replied back to Miklos' answers to his
comments.
- the block queue caching part of Andis O_DIRECT patches. With the
current mess we have with the block queues I'd rather defer that
part for now, hopefull we can still put it in later.
- the btrfs lseek cleanups as part of the lseek series - I think they
are correct, but I fear we might run into a merge mess with them
as Chris said he picked them up for the btrfs tree a while ago.
The tree is at
git://git.kernel.org/pub/scm/linux/kernel/git/hch/vfs-queue.git for-next
and I'd prefer if Stephen could add it to linux-next for a day or two
before pulling it into mainline.
