Subject: flag 128
There is also one weird use of flag 128 in sem_init. Semantically it
encodes "private" so the complement of a shared flag as used for
mutexes:
sem->__val[2] = pshared ? 0 : 128;
Musl only uses this as a Boolean, so the semantic would be the same if
we'd just have
sem->__val[2] = !pshared;
Do you have any recollection if the "128" was needed for
compatibility, or is this just an artefact?
Thanks
Jens
