I'm about to send everyone a patch; can you put that into a kernel and test it out? The "easiest" way I've found to reproduce this bug is to create a bcache, mkfs.ext4 it, run fsstress on the ext4 FS until the cache is full, then umount and re-run mkfs.ext4, which discards the device before formatting. Eventually it'll BUG(). --D On Fri, Jan 24, 2014 at 10:28:03PM -0800, Darrick J.
