Add a test for the SIGSEGV fixed by "mem: keep COW root VMAs writable when premapping". The parent reserves an address range with PROT_NONE and never touches it, so the kernel does not account it (no "ac" flag in smaps). After fork(), the child turns the same range into a writable mapping and fills it with data. CRIU matches COW VMAs by start/end and flags but ignores their protection bits, so the parent's PROT_NONE, not-accountable VMA becomes the COW root of the child's data VMA. On restore the child inherits the root's mapping. Without the fix that mapping is PROT_NONE, so restoring the child's pages into it faults and the test fails at restore; with the fix it passes.
