Subject: - jbd-abort-when-failed-to-log-metadata-buffers.patch removed from -mm tree


The patch titled
     jbd: abort when failed to log metadata buffers
has been removed from the -mm tree.  Its filename was
     jbd-abort-when-failed-to-log-metadata-buffers.patch

This patch was dropped because I don't think we want to go read-only on file data write errors

The current -mm tree may be found at http://userweb.kernel.org/~akpm/mmotm/

Subject: jbd: abort when failed to log metadata buffers
From: Hidehiro Kawai <hidehiro.kawai.ez@...achi.com>

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.
