From 0eadd1028858b193ce8cdc36bf443d39b42141ca Mon Sep 17 00:00:00 2001 From: Jie Liu Date: Mon, 12 Aug 2013 20:49:56 +1000 Subject: [PATCH] xfs: Introduce a new structure to hold transaction reservation items Introduce a new structure xfs_trans_res to hold transaction reservation item info per log ticket. We also need to improve xfs_trans_resv_calc() by initializing the log count as well as log flags for permanent log reservation.
