Did the same to 2.6.27-stable this weekend -
Ignoring the expected Makefile reject, I had one hunk
fail to apply to fs/dcache.c

I "corrected" (quoted since I don't have a clue what
I am doing here) with:

--- fs/dcache.c.orig	2008-10-09 17:13:53.000000000 -0500

 	dentry_stat.nr_dentry++;

 	spin_unlock(&dcache_lock);

Is that same/similar to your "one minor fix"?

Same here - had to disable XFS and just get on with my life.

Not used in a production system here but I am making massive use of
COW to replicate and track changes made in a large (3Gbyte) build system.

What can I say?  It hasn't crashed and burned (yet).
