Hi James,
please explain why is the spinlock^ needed?
There seems to be lot of other places where link_state is not protected,
for example it is evaluated in lpfc_sli4_handle_received_buffer with no lock.

Could you please also add some more description to the of the body your mails,
sometimes  a subject only is not enough.

Thanks,
Tomas
