Update.
2002-06-18 Amos Waterland <apw@us.ibm.com> * sysdeps/pthread/aio_cancel.c (aio_cancel): Add check for invalid file descriptor. * sysdeps/pthread/aio_fsync.c (aio_fsync): Add check for invalid fd; add check for fd not open for writing. * sysdeps/pthread/aio_suspend.c (aio_suspend): Add check for completed element(s) and do not suspend thread if so. Patch heavily modified by drepper. * rt/tst-aio7.c: New file. Regression test for problems which the above three changes fix. * rt/Makefile (tests): Add tst-aio7. * rt/tst-aio6.c: Fix comment.
