Subject: Re: [PATCH v3] lsilogic mpt fusion: mptctl: Fixed race condition
 around mptctl_id variable using mutexes

Hi Julian, all,

I submitted a patch v4 following Julian's review. A function such as 
"mptctl_do_mpt_command" I don't think is a setup function and so the race 
condition (likelihood) remains. Again, this was mainly concerning the 
usage of "mptctl_id" variable in the driver. My objective was just to make 
it as safe as possible and improve it. Please accept my patch v4 should it 
suffice.

Thank you,

Mark
