From 2819b4ae2873d50fd55292877b0231ec936c3b2e Mon Sep 17 00:00:00 2001 From: Mike Christie Date: Tue, 25 May 2021 13:18:17 -0500 Subject: scsi: qedi: Fix TMF session block/unblock use Drivers shouldn't be calling block/unblock session for tmf handling because the functions can change the session state from under libiscsi. iscsi_queuecommand's call to iscsi_prep_scsi_cmd_pdu-> iscsi_check_tmf_restrictions will prevent new cmds from being sent to qedi after we've started handling a TMF. So we don't need to try and block it in the driver, and we can remove these block calls.
