Sat Jun 18 22:45:04 2005 Søren Sandmann <sandmann@redhat.com> * TODO: Updates * configure.ac: Check for Linux 2.6.11 * process.c (get_pidname): Present pid=-1 as [kernel]. * module/sysprof-module.c: Use register_timer_hook() instead of a kernel timer. Set trace.pid to -1 if interrupt happens in kernel.
