PATCH v2 2/8 xfs: Introduce tr_fsyncts to m_reservation

From: Jie Liu <[email protected]>

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.
