lio_listio should emit an event for each individual request in
addition to the global event. * sysdeps/pthread/lio_listio.c (lio_listio): Renamed to lio_listio_internal. Remove mode parameter check. Only set sigevent type ti SIGEV_NONE if LIO_NO_INDIVIDUAL_EVENT is set. (__lio_listio_21): New function. Compatiblity version which sets LIO_NO_INDIVIDUAL_EVENT before calling lio_listio_internal. (__lio_listio_item_notify): New function. * sysdeps/pthread/lio_listio64.c: Define __lio_listio_21 and __lio_listio_item_notify macros. * sysdeps/pthread/Versions: New file. * rt/tst-aio2.c: Adjust test for new semantics of lio_listio. * include/aio.h: Define LIO_NO_INDIVIDUAL_EVENT. * Versions.def: Add GLIBC_2.4 for librt. * rt/Versions: Whitespace fix. * sysdeps/pthread/aio_misc.c: Likewise.
