Subject: [PATCH 13/17] ublk: don't pass ublk_queue to ublk_fetch()
Date: Wed, 17 Sep 2025 19:49:49 -0600	[thread overview]
Message-ID: <20250918014953.297897-14-csander@purestorage.com> (raw)
In-Reply-To: <20250918014953.297897-1-csander@purestorage.com>

ublk_fetch() only uses the ublk_queue to get the ublk_device, which its
caller already has. So just pass the ublk_device directly.
