Hi Filipe,
Thanks for adding a test!
Aside: another similar test could verify that the original function, in
Introduce a test that registers a range of memory for
UFFDIO_WRITEPROTECT_MODE_WP without UFFD_FEATURE_EVENT_REMAP. First
check that the uffd-wp bit is set for every PTE in the range. Then
mremap() the range to a new location and check that the uffd-wp bit is
clear for every PTE in the range.
Run
Since we will replace iptables with nft for wireguard netns testing,
let's also convert the qemu test to use nft at the same time.

Add a test which checks that the kstkesp field in /proc/pid/stat can be
read for all threads of a coredumping process.
