Hmm. This is not what I see in upstream kernel...

Afaics, PTRACE_SYSEMU means:

        - cancel this syscall, and do _not_ report SYSCALL_ENTRY
          to the tracer

        - SYSCALL_EXIT should be reported, but send_sigtrap()
          should be avoied (in case it was SYSEMU_SINGLESTEP).

Correct?

Oleg.
