Subject: [RFC PATCH 01/12] nvme: refactor nvme_alloc_io_tag_set
Date: Sat, 29 Apr 2023 15:09:14 +0530 [thread overview]
Message-ID: <[email protected]> (raw)
In-Reply-To: <[email protected]>
Allow this function to take nr_hw_queues as a parameter. And change all
the callers. This is in preparation to introduce queues which do not
have to be registered with block-layer.
Signed-off-by: Kanchan Joshi <[email protected]>
