Subject: [patch 3/7] mm: do_sync_mapping_range integrity fix
Date: Tue, 21 Oct 2008 19:09:50 +1100 [thread overview]
Message-ID: <20081021081138.983141000@nick.local0.net> (raw)
In-Reply-To: 20081021080947.032757000@suse.de
[-- Attachment #1: mm-do-sync-mapping-range-fix.patch --]
[-- Type: text/plain, Size: 645 bytes --]
Chris Mason notices do_sync_mapping_range didn't actually ask for data
integrity writeout. Unfortunately, it is advertised as being usable for
data integrity operations.
This is a data interity bug.
