Subject: [PATCH 15/17] target/core: Remove the write_pending_status() callback function
Date: Mon, 17 Sep 2018 21:35:52 +0000	[thread overview]
Message-ID: <20180917213554.987-16-bvanassche@acm.org> (raw)

Due to the patch that makes TMF handling synchronous the
write_pending_status() callback function is no longer called.
Hence remove it.
