| H A D | ptrace.c | c0c0b649 Fri Feb 08 06:19:00 CST 2008 Oleg Nesterov <oleg@tv-sign.ru> ptrace_check_attach: remove unneeded ->signal != NULL check
It is not possible to see the PT_PTRACED task without ->signal/sighand under
tasklist_lock, release_task() does ptrace_unlink() first. If the task was
already released before, ptrace_attach() can't succeed and set PT_PTRACED.
Remove this check.
