That's why I asked :-)
Yep, it can be passed to open() and openat(), but it affects all *at()
functions. It's mostly about permission checking, but not supporting this
mode calls for ported packages that check for the *at() functions
existence and implicitly assume O_SEARCH to exist as well. I'm actually
almost surprised that none of the ported code in the repository does that.
This kind of problem is why I had to introduce the
B_ENABLE_INCOMPLETE_POSIX_AT_SUPPORT in the first place.
