Re: xfs Warnings in syslog

[Jeff Liu <jeff.liu@oracle.com>]

Hello,

So It's better to add XFS mailing list to the CC-list. :)

I think this issue has been fixed by upstream commits:

From ff9a28f6c25d18a635abcab1f49db68108203dfb
From: Jan Kara <jack@suse.cz>
Date: Thu, 14 Mar 2013 14:30:54 +0100
Subject: [PATCH 1/1] xfs: Fix WARN_ON(delalloc) in xfs_vm_releasepage()


Thanks,
-Jeff
