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.)

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.
