clone: prepare to recycle CLONE_STOPPED
Ulrich says that we never used this clone flags and that nothing should be
using it.
As we're down to only a single bit left in clone's flags argument, let's add a
warning to check that no userspace is actually using it. Hopefully we will
be able to recycle it.
Roland said:
CLONE_STOPPED was previously used by some NTPL versions when under
thread_db (i.e. only when being actively debugged by gdb), but not for a
long time now, and it never worked reliably when it was used. Removing it
seems fine to me.
[akpm@linux-foundation.org: it looks like CLONE_DETACHED is being used]
