[LTP] [PATCH] aio: Wire up compat_sys_io_pgetevents_time64 for x86

Richard Palethorpe rpalethorpe@suse.com
Tue Sep 21 15:01:27 CEST 2021


The LTP test io_pgetevents02 fails in 32bit compat mode because an
nr_max of -1 appears to be treated as a large positive integer. This
causes pgetevents_time64 to return an event. The test expects the call
to fail and errno to be set to EINVAL.

Using the compat syscall fixes the issue.
