Subject: [PATCH 06/16] RDMA/srpt: Fix handling of command / TMF submission failure
Date: Fri, 25 Jan 2019 18:34:48 +0000 [thread overview]
Message-ID: <20190125183458.220477-7-bvanassche@acm.org> (raw)
If submitting an SRP IU to the target core fails, send the SCSI
response "BUSY" to the initiator instead of not sending any
response.
