Subject: [PATCH v2 3/9] ref_transaction_update(): die on disallowed flags
Date: Sun, 5 Nov 2017 09:42:03 +0100 [thread overview]
Message-ID: <10901328af1e6e04e8c7c7b39977ec85f6c58142.1509870243.git.mhagger@alum.mit.edu> (raw)
In-Reply-To: <cover.1509870243.git.mhagger@alum.mit.edu>
Callers shouldn't be passing disallowed flags into
`ref_transaction_update()`. So instead of masking them off, treat it
as a bug if any are set.
