[GIT PULL] fuse updates for 3.8

[GIT PULL] fuse updates for 3.8

[Miklos Szeredi]

Hi Linus,

Sorry for the late submission.  Most of this was bound for 3.7, which I
missed due to moving house.  I think it makes sense to merge it now
instead of next cycle as there are quite of few other fuse updates
pending.

Please consider pulling

  git://git.kernel.org/pub/scm/linux/kernel/git/mszeredi/fuse.git for-linus

The large part of this pull request is a patch series from Maxim
Patlasov to optimize scatter-gather direct IO.  The rest is small fixes
and cleanups.

There's a one line change outside of fs/fuse to mm/filemap.c which makes
the argument of iov_iter_single_seg_count() const, required by Maxim's
patches.

Thanks,
Miklos

Hi Miklos,

Would you consider the adaptive readdir_plus patch?

Yes, I'm going to go over and review the patches sent in the last month.

Thanks,

Please just send the fixes. We're post-rc3, I'm not willing to take
new code like this. Send the actual new code during the next merge
window.
