We can also add these to an header to include/lapi/ to ensure that they
are defined (we do have these definitions allready in
testcases/kernel/fs/fs_bind/bin/smount.c so technically we just need to
move them there). Then we can get rid of the ifdefs in the test code,
but I'm wondering if the kernel version check is enough to be sure these
flags are implemented (there seems to be no error checking for unknown
flags in fs/namespace.c do_mount() function and it looks like these are
simply ignored).
