Message-ID: <48887776.4080504@hitachi.com> Date: Thu, 24 Jul 2008 21:37:10 +0900 From: Hidehiro Kawai <hidehiro.kawai.ez@...achi.com> To: akpm@...ux-foundation.org, sct@...hat.com Cc: linux-kernel@...r.kernel.org, linux-ext4@...r.kernel.org, jack@...e.cz, jbacik@...hat.com, cmm@...ibm.com, tytso@....edu, adilger@...sterfs.com, snitzer@...il.com, tglx@...utronix.de, yumiko.sugita.yf@...achi.com, satoshi.oshima.fk@...achi.com Subject: [PATCH 1/4] jbd: abort when failed to log metadata buffers If we failed to write metadata buffers to the journal space and succeeded to write the commit record, stale data can be written back to the filesystem as metadata in the recovery phase. To avoid this, when we failed to write out metadata buffers, abort the journal before writing the commit record.
