[git pull] more vfs stuff

[Al Viro <viro@ZenIV.linux.org.uk>]

	Mostly vfsmount-related stuff; some leftovers from mnt_devname
(not all, BTW - there's more pending cleanups around nfs/super.c) plus
pstore fix plus deadlock fix in pivot_root().  The really neat thing is
that now we have no blocking on fs locks under namespace_sem - the only
blocking stuff under it now is kmalloc(), which makes things much more
robust.  Please, pull from the usual place -
git://git.kernel.org/pub/scm/linux/kernel/git/viro/vfs-2.6.git/ for-linus

More to follow tonight - I hoped to push assorted patches accumulated
during the last cycle in this pile, but that'll have to wait until the
next push.

Shortlog:
Al Viro (6):
      kill simple_set_mnt()
      vfs: split off vfsmount-related parts of vfs_kern_mount()
      fix deadlock in pivot_root()
      change the locking order for namespace_sem
      don't pass 'mounting_here' flag to follow_down()
      lose 'mounting_here' argument in ->d_manage()
