During chip reset recovery process, driver notifies the transport layer that remote port no longer exist, by calling fc_remote_port_delete(). When this function is called, it actually delays deletion by "blocking" it. It sets the remote port state to "FC_PORTSTATE_BLOCKED" and sets FC_RPORT_DEVLOSS_PENDING. When driver tries to abort the command by calling its abort handler function, abort handler will wait until remote port state is blocked state or wait for dev_loss_tmo time. Due to this blocking, rport times out and results in an IO failure. This patch adds a check for any active reset process before calling abort handler function.
