Subject: [PATCH 05/11] ALSA: pcm: check for user backed iterator, not specific iterator type
Date: Thu, 30 Mar 2023 10:46:56 -0600 [thread overview]
Message-ID: <20230330164702.1647898-6-axboe@kernel.dk> (raw)
In-Reply-To: <20230330164702.1647898-1-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.
