Subject: [PATCH 6/9] IB/qib: check for user backed iterator, not specific iterator type
Date: Tue, 28 Mar 2023 15:58:08 -0600 [thread overview]
Message-ID: <20230328215811.903557-7-axboe@kernel.dk> (raw)
In-Reply-To: <20230328215811.903557-1-axboe@kernel.dk>
In preparation for switching single segment iterators to using ITER_UBUF,
swap the check for whether we are user backed or not.
