Subject: flood of btrfs WARNINGs in dmesg
Date: Mon, 04 Oct 2010 15:19:41 +0200 [thread overview]
Message-ID: <4CA9D46D.6060309@wpkg.org> (raw)
With 2.6.35.x, I saw warnings like below in dmesg.
With 2.6.36-rc6, I even had a flood of them. Is it something to worry about? What causes it?
You can see more of these under http://www.virtall.com/files/dmesg-btrfs-flood.txt
