Let's test that we can have shared zeropages in our process as long as storage keys are not getting used, that shared zeropages are properly unshared (replaced by anonymous pages) once storage keys are enabled, and that no new shared zeropages are populated after storage keys were enabled. We require the new pagemap interface to detect the shared zeropage. On an old kernel (zeropages always disabled): # ./s390x/shared_zeropage_test TAP version 13 1..3 not ok 1 Shared zeropages should be enabled ok 2 Shared zeropage should be gone ok 3 Shared zeropages should be disabled # Totals: pass:2 fail:1 xfail:0 xpass:0 skip:0 error:0 On a fixed kernel: # ./s390x/shared_zeropage_test TAP version 13 1..3 ok 1 Shared zeropages should be enabled ok 2 Shared zeropage should be gone ok 3 Shared zeropages should be disabled # Totals: pass:3 fail:0 xfail:0 xpass:0 skip:0 error:0 Testing of UFFDIO_ZEROPAGE can be added later.
