[PATCHES] ceph d_name race fixes

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

	Series of race fixes for d_name handling in ceph had been posted
back in February, but apparently had fallen through the cracks - I expected
ceph folks to pull (or cherry-pick) it, they apparently thought I'd send
it to Linus and nobody checked what actually went down...

	I've rebased it to 6.16-rc1, with a couple of cosmetical changes
suggested back then.  Currently it's in
git://git.kernel.org/pub/scm/linux/kernel/git/viro/vfs.git work.ceph-d_name-fixes
Individual patches in followups.

	Folks, could you test and review it?  I really don't care which
tree would it go through, just let's make sure that everyone agrees who
pushes it out...
