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.
