Subject: Re: [PATCH 1/2] pci: host: pci-hyperv: Replace GFP_ATOMIC with GFP_KERNEL in hv_pci_onchannelcallback

Smatch tracks information about every function call.  When a function
pointer is called it maybe looks something like this:

     kernel/module.c |   SYSC_delete_module | (struct module)->exit |    INTERNAL |  -1 |  | void(*)()

So then we just have to know what functions are assigned to
module->exit.

I also filter based on the function signature "void(*)()" because
there are a couple places where we cut and pasted so the structs can
have the same name and function pointer name as a member but take
different arguments.

regards,
dan carpenter
