It doesn't look like there is any reason to do a kmalloc. We can do the byte swap in place and avoid the allocation. This allow us to remove a kmalloc and a memcpy. Signed-off-by:

Rather than preallocating a list of timers and doling them out at runtime, embed a struct timerlist in each object that needs one. A struct sci_timer interface is introduced to manage the timer cancellation semantics which currently need to guarantee the timer is cancelled while holding spin_lock(ihost->scic_lock). Since the timeout functions also need to acquire the lock it currently prevents the driver from using del_timer_sync() for runtime cancellations. del_timer_sync() is used however before the objects go out of scope.

Now that any given object type only has one state_machine we can use container_of() to get back to the given state machine owner. Reported-by:

This conversion was complicated by the fact that the ready state exit routine took unconditional action beyond just stopping the substate machine (like in previous conversions). In order to ensure identical behaviour every state transition needs to be instrumented to catch ready-->!ready transitions and execute scic_sds_port_invalidate_dummy_remote_node() Reported-by:

While cleaning up the driver it is very tempting to convert scic_sds_get_* macros to their open coded equivalent. They are all just pointer dereferences *except* scic_sds_phy_get_port() which returns NULL if the phy is assigned to the dummy port. Clarify this by renaming it to phy_get_non_dummy_port().

Merged states and substates into one state machine, as we always unconditionally transitioned to the substate machine it was straightforward to enter that substate from the starting state. Reported-by:

With these handlers gone the rest of the state handler infrastructure is removed. Added some WARN_ONCEs where previously we would cause NULL pointer dereferences or silently run handlers from a previous state. Reported-by:

Unlike the other conversions this only updates scic_sds_io_request_tc_completion() to call the old state handlers directly (with less verbose names). This was done for future patch readability, the implementations have only minor differences for different completion codes. Without a reference to the function name it would be difficult to dicern which state is being updated. Considered changing the order to look up the completion code before the state but that was not a clean conversion either. Reported-by:

Remove usage of the request substate machine for stp requests, and kill the request substate infrastructure. Similar to the previous conversions this adds the substates to the primary state machine and arranges for the 'started' state to transition to the proper stp substate. Reported-by:
