| | | | | | | | | | | | | | | | | | | | | | | | The PCIE capability offset is saved during PCI bus walking. It will remove an unnecessary search in the PCI configuration space if this value is referenced instead of reacquiring it. Also, pci_is_pcie is a better way of determining if the device is PCIE or not (as it uses the same saved PCIE capability offset).

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We want it to be possible for target_submit_cmd() to return errors up to its fabric module callers. For now just update the prototype to return an int, and update all callers to handle non-zero return values as an error. This is immediately useful for tcm_qla2xxx to fix a long-standing active I/O session shutdown race, but tcm_fc, usb-gadget, and sbp-target the fabric maintainers need to check + ACK that handling a target_submit_cmd() failure due to session shutdown does not introduce regressions (nab: Respin against for-next after initial NACK + update docbook comment + fix double se_cmd init in exception path for usb-gadget) Cc: Chad Dupuis <chad.dupuis@qlogic.com> Cc: Arun Easi <arun.easi@qlogic.com> Cc: Chris Boot <bootc@bootc.net> Cc: Stefan Richter <stefanr@s5r6.in-berlin.de> Cc: Mark Rustad <mark.d.rustad@intel.com> Cc: Sebastian Andrzej Siewior <bigeasy@linutronix.de> Cc: Felipe Balbi <balbi@ti.com> Cc: Andy Grover <agrover@redhat.com> Signed-off-by: Roland Dreier <roland@purestorage.com> Signed-off-by: Nicholas Bellinger <nab@linux-iscsi.org>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Since we set se_session.sess_tearing_down and stop new commands from being added to se_session.sess_cmd_list before we wait for commands to finish when freeing a session, there's no need for a separate sess_wait_list -- if we let new commands be added to sess_cmd_list after setting sess_tearing_down, that would be a bug that breaks the logic of waiting in-flight commands. Also rename target_splice_sess_cmd_list() to target_sess_cmd_list_set_waiting(), since we are no longer splicing onto a separate list.

| | | | | | | | | | | | | | | | | | | | | | | | | | Now that target_submit_cmd() / target_get_sess_cmd() check sess_tearing_down before adding commands to the list, we no longer need the check in qlt_do_work(). In fact this check is racy anyway (and that race is what inspired the change to add the check of sess_tearing_down to the target core).

That function sets se_session.sess_tearing_down, so we can get rid of the qla_target-specific flag, and in the one place that looks at the qla_tgt_sess.tearing_down flag just test se_session.sess_tearing_down instead.
