[GFS2] Detach buf data during in-place writeback
This is patch 5 of 5 for bug #248176 Metadata corruption was occurring because page references weren't being removed in all cases. I previously added a function called detach_bufdata, but I discovered there already WAS a function out there to do the job. It's called gfs2_meta_cache_flush. So I added a call to that to remove the page references. Signed-off-by: Bob Peterson <rpeterso@redhat.com> Signed-off-by: Steven Whitehouse <swhiteho@redhat.com>
