From 0f8468c8bef3d04637c924e7bef20ca53018b319 Mon Sep 17 00:00:00 2001 From: Bob Peterson <rpeterso@redhat.com> Date: Wed, 25 Jul 2007 10:06:22 -0500 Subject: [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.
