[PATCH] pidhash cleanups, tgid-2.5.38-F3
This does the following things:
- removes the ->thread_group list and uses a new PIDTYPE_TGID pid class
to handle thread groups. This cleans up lots of code in signal.c and
elsewhere.
- fixes sys_execve() if a non-leader thread calls it. (2.5.38 crashed in
this case.)
- renames list_for_each_noprefetch to __list_for_each.
- cleans up delayed-leader parent notification.
- introduces link_pid() to optimize PIDTYPE_TGID installation in the
thread-group case.
I've tested the patch with a number of threaded and non-threaded
workloads, and it works just fine. Compiles & boots on UP and SMP x86.
The session/pgrp bugs reported to lkml are probably still open, they are
the next on my todo - now that we have a clean pidhash architecture they
should be easier to fix.
