From 20f12d8ac01917d96860f352f67eddd912df0afb Mon Sep 17 00:00:00 2001 From: Mitsuo Hayasaka Date: Mon, 6 Feb 2012 12:50:07 +0000 Subject: xfs: change available ranges of softlimit and hardlimit in quota check In general, quota allows us to use disk blocks and inodes up to each limit, that is, they are available if they don't exceed their limitations. Current xfs sets their available ranges to lower than them except disk inode quota check. So, this patch changes the ranges to not beyond them.
