NetBSD recently added SET, CLR, ISSET to sys/types.h (only if _KERNEL
is defined). I'd like to do something similar in FreeBSD. I see no
reason to needless deviate from NetBSD here. One could make an
argument for lots of different files, but at the end of the day does
it really matter enough to justify having it be different than NetBSD?
Here's my proposed diff, inline, for your consideration:
Who not create abstract framework for work with bitmask more then 64bits
NOTE: That /* !_KERNEL */ should have the '!' removed, but I didn't
want to confuse things by doing that too.
Comments?

size?
similar this:
#define_bitmask(name,size) char name[(size/8)+1];
#define set_bit(bimask,no) { bitmask[(no/8)] |= 1<<(no%8); }
#define clr_bit(bitmask,no) { bitmask[(no/8)] &= ~(1<<(no%8)); }
static inline isset_bit(char *bitmask, no) {
return bitmask[(no/8)] & 1<<(no%8);
}
