Subject: [PATCH 02/14] nvmet: remove repeated call for error log page
Date: Sun, 27 Jun 2021 22:08:05 -0700	[thread overview]
Message-ID: <20210628050817.19788-3-chaitanya.kulkarni@wdc.com> (raw)
In-Reply-To: <20210628050817.19788-1-chaitanya.kulkarni@wdc.com>

Return status from nvmet_execute_get_log_page_error() and complete the
request in nvmet_execute_get_log_page(). This reduces number of
repeated nvmet_req_complete() calls for log page handlers.
