Update.
2003-12-23 Jakub Jelinek <jakub@redhat.com> * sysdeps/unix/sysv/linux/raise.c (raise): Protect pid = selftid setting with __ASSUME_TGKILL || defined __NR_tgkill. If pid is 0, set it to selftid. * sysdeps/unix/sysv/linux/getpid.c (really_getpid): Make inline. Don't set self->pid but self->tid. If self->pid == 0 and self->tid != 0, return self->tid without doing a syscall. * descr.h (struct pthread): Move pid field after tid. * Makefile (tests): Add tst-raise1. * tst-raise1.c: New file.
