Ug, binary and logical ANDs should not be combined. Just looks nasty.
What about:

	softirqd = !!(IS_ENABLED(CONFIG_PREEMPT_RT_FULL) &&
			current == this_cpu_ksoftirqd());

My way looks prettier to me, but I seem to be the only who thinks so
(this is not the first time it got a gripe), so I'll change it ;-)

I shouldn't have said it looks nasty. It actually does look pretty, in
an artistic kind of way. It's just not very comprehensible.
