    Subject[PATCH 10/51] [GFS2] Detach buf data during in-place writeback
    From: Bob Peterson <>

    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.
