From 70b5437653d9c6c8de287affd38836cce98ebde5 Mon Sep 17 00:00:00 2001 From: Mitsuo Hayasaka Date: Mon, 6 Feb 2012 12:51:05 +0000 Subject: [PATCH] xfs: cleanup quota check on disk blocks and inodes reservations This patch is a cleanup of quota check on disk blocks and inodes reservations, and changes it as follows. (1) add a total_count variable to store the total number of current usages and new reservations for disk blocks and inodes, respectively. (2) make it more readable to check if the local variables softlimit and hardlimit are positive. It has been changed as follows. if (softlimit > 0ULL) -> if (softlimit) if (hardlimit > 0ULL) -> if (hardlimit) This is because they are defined as xfs_qcnt_t which is unsigned.
