Subject: [RFC PATCH liburing v1 4/4] test/io_uring_{enter,setup,register}: Use the exported syscall functions
From: Ammar Faizi <ammarfaizi2@...weeb.org>
These tests use the internal definition of __sys_io_uring* functions.
A previous commit exported new functions that do the same thing with
those __sys_io_uring* functions. Test the exported functions instead of
the internal functions.
No functional change is intended.
