It is a build-time assertion, if you want. :)
And git grep says that mips abuses this notation: arch/mips/include/asm/kvm_host.h:#define MS_TO_NS(x) (x * 1E6L)
I do not have cross-compiler set up to check whether this is a real issue because include/media/rc-core.h defines the same macro correctly so the real code might end up using the right variant. -- Michal Hocko SUSE Labs
