Begin forwarded message: Date: Wed, 12 Jan 2011 12:34:33 -0500 From: Valdis.Kletnieks@xxxxxx To: Alexander Viro <viro@xxxxxxxxxxxxxxxxxx>, Neil Brown <neilb@xxxxxxx> Cc: linux-kernel@xxxxxxxxxxxxxxx, linux-fsdevel@xxxxxxxxxxxxxxx, linux-raid@xxxxxxxxxxxxxxx Subject: linux-next - WARNING: at fs/block_dev.c:824 bd_link_disk_holder+0x92/0x1ac() Seen in a boot of yesterday's linux-next. The 'W' flag was due to the already-reported 'WARNING: at kernel/workqueue.c:1202 worker_enter_idle'. Not sure if it's a block_dev or dm/LVM issue, so I'm cc:'ing both groups. I wonder if the fact I still have 'CONFIG_DEVTMPFS=n' is involved (it's apparently ticking off dracut before and after the warning).
