--- Comment #1 from Mateusz Guzik <mjg at FreeBSD.org> ---
Hi there, thanks for the report. This one is definitely a false-positive. The
code locks in the interlock to call vdropl, which returns with it unlocked. If
vdropl was not dropping the lock, the code would already be buggy due to
leaking the lock.
