Robert Jennings 3c887e8a1a [SCSI] ibmvscsi: Prevent IO during partner login ... By setting the request_limit in send_srp_login to 1 we allowed login requests to be sent to the server adapter. If this was not an initial login, but was a login after a disconnect with the server, other I/O requests could attempt to be processed before the login occured. These I/O requests would fail, sometimes resulting in filesystems getting marked read-only. To address this we can set the request_limit to 0 while doing the login and add an exception where login requests, along with task management events, are always passed to the server. There is a case where the request_limit had already reached 0 would result in all events being sent rather than returning SCSI_MLQUEUE_HOST_BUSY; this has also been fixed by this patch.
