Hi!
Pushed with a minor change, thanks.

We should check if the addr is valid before we attemp to unmap it in the
setup() so I've added:

diff --git a/testcases/kernel/syscalls/mmap/mmap22.c b/testcases/kernel/syscalls/mmap/mmap22.c

        if (addr == MAP_FAILED && errno == EINVAL)

        SAFE_MUNMAP(addr, 1);
 }
