Description

I'm running the unstable branch and I'm seeing in my dmesg:

I joined the #btrfs channel and they said:

20:00 < widodh> I've just upgraded to 2.6.37-rc1 to test Ceph, but I'm seeing this right now in my dmesg: 
                http://pastebin.com/3HiGiNgy ( inode.c / btrfs_orphan_commit_root )
20:01 < josef> hrm looks like sage screwed something up with async commit
20:02 < widodh> aha, file it over there then?
20:03 < josef> well tell sage about it, he's the one who wrote the code so he'll probably be able to fix it quicker
20:03 < widodh> yes, sure. I thought it was a btrfs bug, that's why I came along here
20:03 < widodh> thanks!
20:05 < josef> well it is a bug in btrfs, but he will be able to fix it quicker than i will

I've seen this while I had one VM running (qemu-rbd) with bonnie++ in it.
