A non-zero queuecommand() return code means 'busy', i.e. the command hasn't been submitted. So any command which should be failed need to be completed via the ->scsi_done() callback with the appropriate result code set.

The message byte setting always devolves to COMMAND_COMPLETE so we can drop setting the message byte in the SCSI result. Link: https://lore.kernel.org/r/20210113090500.129644-30-hare@suse.deReviewed-by:

CMD_ACCEPT_MSG is an internal definition and most certainly not a SCSI status. As the latter gets set during command completion we can drop the assignment here. Link: https://lore.kernel.org/r/20210113090500.129644-26-hare@suse.deReviewed-by:

The aacraid controller is a RAID controller and the driver will never see any SCSI messages. Plus it's quite pointless to set the message byte if the host byte is already set, as the latter takes precedence during error recovery. Drop the message byte values for the final result.

The gdth driver refers to a SCSI parallel, PCI-only HBA RAID adapter which was manufactured by the now-defunct ICP Vortex company, later acquired by Adaptec and superseded by the aacraid series of controllers. The driver itself would require a major overhaul before any modifications can be attempted, but seeing that it's unlikely to have any users left it should rather be removed completely.

transport_handle_cdb_direct() uses in_interrupt() to detect if it is safe to sleep. It produces a stack trace and returns with an error which is clearly for debugging. The usage of in_interrupt() in drivers is phased out and Linus clearly requested that code which changes behaviour depending on context should either be separated or the context be conveyed in an argument passed by the caller, which usually knows the context. transport_handle_cdb_direct() has a comment saying that it may only be invoked from process context. It invokes transport_generic_new_cmd() which performs GFP_KERNEL memory allocations. in_interrupt() does not detect all the contexts where it is invalid to sleep (for the blocking GFP_KERNEL allocation) as it fails to detect sections with disabled preemption. Replace the in_interrupt() based check with a might_sleep() annotation. Link: https://lore.kernel.org/r/20201220203638.43615-7-bigeasy@linutronix.deSigned-off-by:

target_submit_cmd_map_sgls() uses in_interrupt() to crash if it returns true. The usage of in_interrupt() in drivers is phased out and Linus clearly requested that code which changes behaviour depending on context should either be separated or the context be conveyed in an argument passed by the caller, which usually knows the context. The usage of in_interrupt() is clearly for debugging. might_sleep() is better at this because it also detects other contexts in which it is not allowed to sleep, like preempt-disabled section. Replace BUG_ON(in_interrupt) with might_sleep(). Link: https://lore.kernel.org/r/20201220203638.43615-6-bigeasy@linutronix.deSigned-off-by:

The usage of in_interrupt() in drivers is phased out and Linus clearly requested that code which changes behaviour depending on context should either be separated or the context be conveyed in an argument passed by the caller, which usually knows the context. core_alua_check_nonop_delay() has two callers: - target_submit_cmd_map_sgls() Kernel doc says it that it must be called from process context. Also has a BUG_ON(in_interrupt()). - iscsit_setup_scsi_cmd() Invokes iscsit_add_reject_cmd() which does GFP_KERNEL allocation and target_cmd_init_cdb() which may do GFP_KERNEL allocations. Remove the in_interrupt() check because all callers are from preemptible context. Link: https://lore.kernel.org/r/20201220203638.43615-5-bigeasy@linutronix.deSigned-off-by:

The return value of iscsit_check_session_usage_count() is only checked if it was not allowed to sleep. If it returns `2' then a timer is prepared. If it returns something else or if it was allowed to sleep then it is ignored. Let iscsit_check_session_usage_count() return true if it needs to arm the timer - otherwise false. This simplifies the code flow of the only caller. Link: https://lore.kernel.org/r/20201220203638.43615-4-bigeasy@linutronix.deSigned-off-by:

iscsit_check_session_usage_count() uses in_interrupt() to find out if it is safe to invoke wait_for_completion(). The usage of in_interrupt() in drivers is phased out and Linus clearly requested that code which changes behaviour depending on context should either be separated or the context be conveyed in an argument passed by the caller, which usually knows the context. There is only one caller of iscsit_check_session_usage_count() which already has an argument indicating if it is safe to sleep. Extend iscsit_check_session_usage_count() by an argument indicating if it may sleep. Link: https://lore.kernel.org/r/20201220203638.43615-3-bigeasy@linutronix.deSigned-off-by:

iscsit_close_session() uses in_interrupt() to decide if it needs to check the return value of iscsit_check_session_usage_count() if it was not able to sleep. The usage of in_interrupt() in drivers is phased out and Linus clearly requested that code which changes behaviour depending on context should either be separated or the context be conveyed in an argument passed by the caller, which usually knows the context. iscsit_close_session() has two callers: - iscsit_handle_time2retain_timeout() A timer_list callback. - iscsit_close_connection() Runs in preemptible context, acquires a mutex. Add an argument to iscsit_close_session() indicating if sleeping is possible. Link: https://lore.kernel.org/r/20201220203638.43615-2-bigeasy@linutronix.deSigned-off-by:
