Will that actually build correctly if it's an embedded system or something build with
CONFIG_PROC_FS=n? I'd expect that to die a horrid death while linking vmlinx due
to stuff inside that #ifdef calling symbols only present with PROC_FS=m/y.

In general, inline ifdef's are frowned upon, so if you come across one in the kernel
source, that's probably a *big* hint that either (a) refactoring the code to eliminate
an inline ifdef was just too ugly to be allowed to live or (b) you *have* to put a guard
around it because you're guaranteed a build failure otherwise.
