fibre channel sync cache question

Hello All,

Using fibre channel disks, I've noticed that when the system shuts down that the sd_driver issues a sync cache command to the device. I've also noticed that when the lldd is removed via rmmod that this sync cache is not executed. I would think that the sync cache would be desirable under this circumstance.

Was it a conscious decision to not have sync cache executed during module unload?

Is it desirable?

(There are various reasons why it doesn't work. The rport port_state is not ONLINE, the module is being unloaded so that a reference cannot be acquired, the sdev state is SDEV_CANCEL. Three strikes and you're out?)
