From f755503206ef705c20db622637d80a3e1b94a6f5 Mon Sep 17 00:00:00 2001 From: Brian Foster Date: Fri, 21 Dec 2012 10:45:17 -0500 Subject: [PATCH] xfs: remove int casts from debug dquot soft limit timer asserts The int casts here make it easy to trigger an assert with a large soft limit. For example, set a >4TB soft limit on an empty volume to reproduce a (0 > -x) comparison due to an overflow of d_blk_softlimit.
