My intent is to MFC this change after FreeBSD 7.0 is released. This
brings up some questions and problems. This change adds
_pthread_mutex_init_calloc_cb as a private interface that is implemented
by lib{c,thr,kse}, so from the user's perspective there is no API
change, but of course the libraries have to be in sync with each other.
1) Do we need to introduce a new namespace to src/lib/libc/Versions.def
for such a change?
2) If we do introduce a new namespace in RELENG_7, does that mean that
every time we MFC an interface, we have to add a new namespace?
3) Suppose that we do add the FBSDprivate_1.1 namespace. It it a
successor to FBSD_1.1 or FBSDprivate_1.0? It appears that we cannot
have it both ways, which leads me to suspect that FBSDprivate_1.0 should
not be a successor to FBSD_1.0 (i.e. it should have no dependencies),
and that FBSDprivate_1.1 should be a successor to FBSDprivate_1.0.
FWIW, it looks like once we get the Versions.def issues figured out, I'm
guessing that _pthread_mutex_init_calloc_cb should be in
src/lib/libc/stdlib/Symbol.map since its definition is in the stdlib
directory rather than the gen directory.
Thanks,
Jason
