Hi,
does it make sense to add that syscall ? This syscall is present
on FreeBSD and allows the caller to add entries to ktrace record. This is
sometimes handy for debugging. There are hooks for this in e.g.
basesrc/lib/libc/stdlib/malloc.c, FreeBSD folks probably use this in other
places too.

I'm not quite convinced this is usable enough, but since all necessary
support in kernel is there now, it would be very easy to add.

Opinions ?
