exit: Coredumps reach do_group_exit
The comment about coredumps not reaching do_group_exit and the corresponding BUG_ON are bogus. What happens and has happened for years is that get_signal calls do_coredump (which sets SIGNAL_GROUP_EXIT and group_exit_code) and then do_group_exit passing the signal number. Then do_group_exit ignores the exit_code it is passed and uses signal->group_exit_code from the coredump. The comment and BUG_ON were correct when they were added during the 2.5 development cycle, but became obsolete and incorrect when get_signal was changed to fall through to do_group_exit after do_coredump in 2.6.10-rc2. So remove the stale comment and BUG_ON Fixes: 63bd6144f191 ("[PATCH] Invalid BUG_ONs in signal.c") History-Tree: https://git.kernel.org/pub/scm/linux/kernel/git/tglx/history.git Link: https://lkml.kernel.org/r/20220103213312.9144-2-ebiederm@xmission.com Signed-off-by: "Eric W.
