input: redefine INPUT_COMPAT_TEST as in_compat_syscall() (f4056b52) · Commits · 戴 / test

The input compat code should work like all other compat code: for 32-bit syscalls, use the 32-bit ABI and for 64-bit syscalls, use the 64-bit ABI. We have a helper for that (in_compat_syscall()): just use it. Signed-off-by:
