Alan (Stern), don't get you knickers in a knot because someone completely
unfamiliar with USB/SCSI error handling paths mischaracterised a massive stack
trace full of USB and SCSI functions leading up erroneously into the filesystem
sync code.
However, given you comment, I'd love to know why Alan (Cox) went and
characterised this as a filesystem/XFS bug. I can't reassign it to the block
layer because normal bugzilla users can't change the product field.
FWIW, seeing as the person who raised this bug is now playing bugzilla bingo,
here's the original XFS bz where this was raised back in january:
