Originally GWBITMASK was capable of extending itself dynamically, a functionality that in practice was never used, and that, in fact, was broken. As GWBITMASK is used for a single purpose inside MaxScale, its size is now fixed at 256 bits, which is sufficient for 256 threads. Its fixed size removes a few potential error situations that now then do not need to be dealt with. And in principle is also more performant. In a separate change, bitmask_free will be renamed to bitmask_finish, as contrary to free-functions in general, the function does not free the argument, but only its data. The implementation will be empty, but the function left in place for symmetry reasons (alloc/free, init/finish).
