Roland Dreier d6dfc868bc target: Allow for target_submit_cmd() returning errors ... 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>		2012-07-17 17:05:05 -07:00
