Hi Noah,
The goal here is to move to the standard atomics, not to invent our own set for
convenience or just for fun to be different etc. There were 2 uses of atomic_bit_set
in all of GLIBC, and I cannot believe that atomic_fetch_or (&x, 1 << bit) could cause
any confusion given that it is very similar to x |= 1 << bit. We don't wrap such
expressions in macros like bitset (x, bit) either - it just doesn't make sense.
As I mentioned, I'll use EXITING_BITMASK rather than 1 << EXITING_BIT.
Cheers,
Wilco
