Subject: [PATCH v15 11/12] null: Enable trace capability for null block
Date: Wed, 6 Sep 2023 22:08:36 +0530 [thread overview]
Message-ID: <20230906163844.18754-12-nj.shetty@samsung.com> (raw)
In-Reply-To: <20230906163844.18754-1-nj.shetty@samsung.com>
This is a prep patch to enable copy trace capability.
At present only zoned null_block is using trace, so we decoupled trace
and zoned dependency to make it usable in null_blk driver also.
