Update.
1999-08-15 Ulrich Drepper <drepper@cygnus.com> * sysdeps/unix/sysv/linux/aio_sigqueue.c: Take extra parameter and initialize si_pid from it. * sysdeps/generic/aio_sigqueue.c (__aio_sigqueue): Take extra parameter. * rt/aio_misc.c (__aio_enqueue_request): Initialize caller_pid. * rt/aio_misc.h (struct waitlist): Add caller_pid element. (struct requestlist): Likewise. Adjust prototypes of __aio_notify_only and __aio_sigqueue. * rt/notify.c (__aio_notify_only): Take extra parameter. Pass it to __aio_sigqueue. (__aio_notify): Pass caller PID to __aio_notify_only. * rt/aio_suspend.c: Initialize caller_pid. * rt/lio_listio.c: Likewise. * rt/lio_listio64.c: Likewise. * rt/lio_listio.c: If nothing has to be done free mutex before signalling. * rt/lio_listio64.c: Likewise.
