From 3d3c8b5222b92447bffaa4127ee18c757f32a460 Mon Sep 17 00:00:00 2001 From: Jie Liu Date: Mon, 12 Aug 2013 20:49:59 +1000 Subject: xfs: refactor xfs_trans_reserve() interface With the new xfs_trans_res structure has been introduced, the log reservation size, log count as well as log flags are pre-initialized at mount time. So it's time to refine xfs_trans_reserve() interface to be more neat. Also, introduce a new helper M_RES() to return a pointer to the mp->m_resv structure to simplify the input.
