[git pull] more vfs stuff

[git pull] more vfs stuff

[Al Viro]

	Misc stuff missed in the previous pile (including fixup for 9p
breakage).  The last part in sysvfs series replaced with akpm's version
(with its whitespace fixes) with bogus include _not_ added.  Freeze
stuff still pending; unfortunately, I've found a hole in my variant ;-/
I know how to fix that, but I'd rather not send an untested locking change.
It *is* needed in this cycle, since the current variant is simply broken -
for example, try Alt-Sysrq-Emergency Thaw and it'll reliably deadlock ;-/

Please, pull from usual place -

[git pull] more vfs stuff

[Al Viro]

	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()
