commit	2e2ba22ea4fd4bb85f0fa37c521066db6775cbef

removed member session from signal_struct. This results in
compilation error for sid() on latest kernel.

I haven't found the replacement for the member or alike function.
Guess need to make it available under %kernel_v or other solution
if someone had.

Regards,
Wenji
