3.11.10.13 -stable review patch. If anyone has any objections, please let me know.
------------------ From: Nicholas Bellinger <[email protected]> commit f15e9cd910c4d9da7de43f2181f362082fc45f0f upstream. This patch fixes a bug where se_cmd descriptors associated with a Task Management Request (TMR) where not setting CMD_T_ACTIVE before being dispatched into target_tmr_work() process context. This is required in order for transport_generic_free_cmd() -> transport_wait_for_tasks() to wait on se_cmd->t_transport_stop_comp if a session reset event occurs while an ABORT_TASK is outstanding waiting for another I/O to complete.
