[GIT PULL] vfs patches for 4.11

[Miklos Szeredi]

Hi Al,

Please pull from:

  git://git.kernel.org/pub/scm/linux/kernel/git/mszeredi/vfs.git for-viro

This contains:

 - preparation for using tmpfile for regular file copy-up on overlayfs
 - freeze protection fixes
 - preparation for intercepting certain ops for consistent handling of r/o opens
   on overlayfs

Thanks,
Miklos

The last one could have a better summary, but anyway - pulled.

Al,

Please excuse my impatience, but do you plan to send these out to
Linus for 4.11?

If not, Miklos, could possibly ask Linus to pull overlayfs-next, which have been
soaking in linux-next for a while now.

overlayfs-next contains only my 4 VFS patches above, which are not that
controversial IMO.

It'd be nice to get rid of the "big copy up lock" for 4.11.

Thanks,
Amir.

Yes.  As the matter of fact, it will be one of the pull requests in today's
pile.

Cool.

Miklos,

This vfs pile was already pulled.
Could you please follow up with overlayfs 4.11 pull request.

I also verified that overlayfs-next and rebased-statx have no conflicts
(copy_up.c is correctly auto-merged)
and re-tested concurrent copy up and -g overlay/quick with the test merge.

Thanks,
Amir.
