Lustre discuss - Oct 2006 - BUG: warning at fs/inotify.c:255/inotify_d_instantiate()

Hi,

I''m hitting a problem with lustre 1.4.7.1 on 2.6.18 as client. I
thought this was a known issue but I can''t seem to find it again.

When I run bonnie on the client I get the following:

BUG: warning at fs/inotify.c:255/inotify_d_instantiate()

[ 995.557024]

This is because definition of DCACHE_INOTIFY_PARENT_WATCHED clashes with
DCACHE_LUSTRE_INVALID.
You need to make them different numbers, not 0x20 both.
