[cifs-protocol] SMBv1 multiple lock cancel behavior

Hello,
I've got yet another byte range locking question.
MS-CIFS (v0.1) states in section 2.2.4.32.1:
"If the Locks vector contains one and only one entry
(NumberOfRequestedLocks ==
1) and TypeOfLock has the CANCEL_LOCK bit set, the client is requesting
that the
server cancel a previously requested but unacknowledged lock."
My newly pushed smbtorture4 test, part of RAW-LOCK-ASYNC, shows a W2K8R2
server accepting a request with the CANCEL_LOCK bit set that contains
multiple entries in the lock array, ie NumberOfRequestedLocks == 2. The
server then seems to cancel the first outstanding lock and return
SUCCESS.
