[Bug tapsets/6991] New: accept system call missed on 2.6.27

[mjw at redhat dot com]

2.6.27 introduced sys_paccept() and rewrote sys_accept() to be just a
call-through to do_accept(). In the case sys_socketcall/SYS_ACCEPT is used it
bypasses sys_accept and sys_paccept completely and directly calls do_accept. See
http://lwn.net/Articles/279837/

This means that on i386 at least we are missing any accept syscalls. Resulting
in a FAIL: 32-bit net1 testcase from syscalls.exp.

Note that there is another rewrite underway to reintroduce accept4:
http://lwn.net/Articles/304767/ It hasn't hit the upstream kernel yet. But
should be watched to make sure any fix to accept syscall tracing hooks into the
right place.

Fixed in commit 9f61c5d by adding support for sys_accept4.  The net1 test now
passes on 32-bit & 64-bit versions of f11 (2.6.30.9-90) and rhel5
(2.6.18-164.2.1.el5).
