Merge branch 'for-linus-2' of git://git.kernel.org/pub/scm/linux/kernel/git/viro/vfs

Pull VFS fixes and cleanups from Al Viro.

Most of this is the series to remove sync_supers() and the
->write_supers VFS callback from Artem Bityutskiy.  One commit to do the
actual removal work, a whole series of commits to fix up stale comments
etc all over the tree.

There's also a regression fix for an incorrect use of mnt_drop_write()
in do_dentry_open().
