Subject: [PATCH v2] xfs: fix assertion failure at xfs_setattr_nonsize
Date: Sat, 23 Nov 2013 00:08:06 +0800 [thread overview]
Message-ID: <528F8166.9060803@oracle.com> (raw)
From: Jie Liu <jeff.liu@oracle.com>
For CRC enabled v5 super block, change a file's ownership can simply
trigger ASSERT failure at xfs_setattr_nonsize() if both group and
project quota are enabled, i.e,
[ 305.337609] XFS: Assertion failed: !XFS_IS_PQUOTA_ON(mp), file: fs/xfs/xfs_iops.c, line: 621
[ 305.339250] Kernel BUG at ffffffffa0a7fa32 [verbose debug info unavailable]
[ 305.383939] Call Trace:

[ 305.399870] RIP [<ffffffffa0a7fa32>] assfail+0x22/0x30 [xfs]
This fix adjust the assertion to check if the super block support both
quota inodes or not.
