With this fix, the same test produces more usable diagnostic output: # get_syscall_info.c:209:get_syscall_info:Expected exp_args[2] (3134324433) == info.entry.args[1] (18446744072548908753) Link: https://lore.kernel.org/r/20250108170757.GA6723@strace.io Fixes: b5bb6d3068ea ("selftests/seccomp: fix 32-bit build warnings") Signed-off-by: Dmitry V.
