This entry is being used for tracking a regression from 2.6.31.  Please don't
close it until the problem is fixed in the mainline.

Note that Sage reported in http://marc.info/?l=linux-kernel&m=125696970418300&w=4
that he saw this with 2.6.31.   So at minimum it's not a regression from 2.6.31; possibly 2.6.30 --- we need more data, though.
Comment 2 Chris Mason 2009-11-20 15:19:15 UTC
This is a btrfs bug, and was specific to ceph's use of btrfs userland transactions.  We were leaving current->journal_info set after returning from the kernel which ext3 (rightly) faulted on.

It is fixed in 2.6.32-rc7 and higher.
