Subject: [PATCH v2 2/8] xfs: Introduce tr_fsyncts to m_reservation
Date: Fri, 17 May 2013 13:38:59 +0800 [thread overview]
Message-ID: <5195C273.1050703@oracle.com> (raw)
From: Jie Liu <jeff.liu@oracle.com>
A preparation step.
For now fsync_ts transaction use the pre-calculated log reservation
size of tr_swrite.
This patch introduce a new item tr_fsyncts to mp->m_reservations
structure so that we can fetch the log reservation value for it
in a same manner to others.
