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

Well - good question - access should be under lock, and it wouldn't
surprise me if there are some cases, especially read checks, where it
isn't. In most cases, this bad behavior works, as the variable doesn't
change often, and even when it does, there's very long time delays
before something would reference the change. Not trying to say it
shouldn't be fixed, but rather why it hasn't been an issue. This one
will take a little bit to clean up - it reached this point historically
over many successive changes.
Yes, I'll add a little meat to future patches.

OK, makes sense, I have found at least one place where is a spinlock used,
his is a start for an longer process - I'm fine with the explanation.
and also with your response in 7/21+10/21.

Add Lancer Temperature Event support to the lpfc driver
This will detect and send an async event if overtemp is detected
