Subject: [PATCH 42/60] xfs: split out on-disk transaction definitions
Date: Wed, 19 Jun 2013 14:50:50 +1000 [thread overview]
Message-ID: <1371617468-32559-43-git-send-email-david@fromorbit.com> (raw)
In-Reply-To: <1371617468-32559-1-git-send-email-david@fromorbit.com>
From: Dave Chinner <dchinner@redhat.com>
There's a bunch of definitions in xfs_trans.h that define on-disk
formats - transaction headers taht get written into the log, log
item type definitions, etc. Split out everything into a separate
file so that all which remains in xfs_trans.h are kernel only
definitions.
Also, remove the duplicate magic number definitions for
XFS_TRANS_HEADER_MAGIC...
