--- Comment #1 from Konstantin Belousov <kib at FreeBSD.org> ---
The D_INIT flag might be set by another thread while we unlocked dev_mtx in the
D_NEEDGIANT block.  This is a common kernel pattern, unlock, do sleepable
resource allocation, relock, and then recheck the original condition which
might be invalidated by other thread meantime.
