I'm getting selftests build errors:
uffd-unit-tests.c: In function ‘uffd_register_rwp’:
uffd-unit-tests.c:624:25: error: ‘UFFDIO_REGISTER_MODE_RWP’ undeclared (first use in this function); did you mean ‘UFFDIO_REGISTER_MODE_WP’?
624 | .mode = UFFDIO_REGISTER_MODE_RWP,
| ^~~~~~~~~~~~~~~~~~~~~~~~
| UFFDIO_REGISTER_MODE_WP
uffd-unit-tests.c:624:25: note: each undeclared identifier is reported only once
<etc>
Seems that tools/include/uapi/linux/userfaultfd.h needs updates from
include/uapi/linux/userfaultfd.h?
I'll disable this patch for now.
