[Unionfs] oops I've been noticing

[Shaya Potter]

sorry for no more info, but I've been noticing an oops lately.

if I create a mount w/ multiple branches via the mount command, but one
of the dirs doesn't exist yet, so I then go to make it, and redo the
mount command, and then do a unionctl --list, I can regularly (not
always) trigger an oops.

just wondering if anyone else has seen this, haven't had a chance to
investigate it as needed to do some other testing when this was
happening, so just ignored it and rebooted when it occured.
