Hmm. I do think the quota list handling has some odd things going on.
And it did change with the whole ->dq_free thing.

Some of it is just bad:

          /* sanity check */

is done under a spinlock, and if it ever triggers, the machine is
dead. Dammit, I *hate* how people use BUG_ON() for assertions. It's a
disgrace. That should be a WARN_ON_ONCE().

And it does have quite a bit of list-related changes, with the whole
series from Baokun Li changing how the ->dq_free list works.

The fact that it consistently bisects to the merge is still odd.
