Ly" For write_pending if the queue is down or client failed then return -EIO so that LIO can properly process the completed command. Prior we returned 0 since LIO could not handle it properly. Now with: target: Fix unknown fabric callback queue-full errors that patch addresses LIO's ability to handle things right. Signed-off-by: Bryant G.
