Comparing this to what I had before, I noticed syscall_get_return_value()
is missing.
Yes - I only added the bare minimum I needed to compile.
Upon closer look, we don't need it (yet), as we don't select any
of GENERIC_ENTRY, HAVE_ARCH_TRACEHOOK, or HAVE_SYSCALL_TRACEPOINTS,
but why not add it while we're at it?
I can do that - the trouble with this entire series is that I can't
meaningfully test anything. But syscall_get_return_value() isn't that
difficult.
Cheers,
Michael
