[git pull] vfs.git part 1

[Al Viro]

	This cycle a lot of stuff sits on topical branches, so I'll be
sending more or a less pull request per branch.  If you prefer a single
pull request in such situations for the future, please tell.  This is
the first pile; more to follow in a few.  In this one are several misc
commits from early in the cycle (before I went for separate branches) +
rework of mntput/dput ordering on umount, switching to use of fs_pin
instead of convoluted games in namespace_unlock().  Please, pull from
git://git.kernel.org/pub/scm/linux/kernel/git/viro/vfs.git for-linus
