Comment 1 Mark Wielaard 2007-03-22 10:08:46 UTC 
This is related to the various syscall discussions in the past:


- http://sources.redhat.com/ml/frysk/2006-q1/msg00091.html
  (About system call handling in Frysk)
- http://sources.redhat.com/ml/frysk/2006-q3/msg00305.html
  (get syscall num in updateSyscallExit)
- http://sourceware.org/ml/frysk/2006-q3/msg00510.html
  (System call number cached with help from SyscallObserver)
- bug #3185 (ftrace printing deficiencies)
