I got no response from the glibc people on this and the kernel-newbies
list appears dead so I thought I'd try here since these calls are/were
actually kernel based to begin with. Why are they no longer available in
user space and what is one supposed to use now?

Thanks
Mark

There was talk of a libarch for these sorts of things.  Don't know if 
that ever happened.

In general, none of the kernel synchronization-type functions should 
have been used in userspace since they often depend on infrastructure 
which is only in the kernel in order to work properly. The new headers 
installation system strips out any code intended for kernel use only 
from the userspace-visible headers.

(Not to mention the licensing issues - the kernel is GPL, not LGPL, so 
only GPL programs could have legally done so in the first place.)
