Subject: [BUG][data=journal] WARN_ON(PageChecked(page)) in ext4_releasepage() when we run xfstests #247
Date: Thu, 7 Mar 2013 20:33:57 +0800 [thread overview]
Message-ID: <20130307123356.GD2800@gmail.com> (raw)
Hi all,
I hit this WARN_ON in 3.8 kernel and dev branch. The WARN_ON is hard to
be triggerred because I run test case 8 times to hit it. Here is the
messages from dmesg.
*One Big Note*
Although we get the warning message, the test can pass.
wenqing: run xfstest 247
