Add linux/userfaultfd.h to criu sources. This header is a part of the kernel API and I see nothing wrong to have in the repo. Why we want to do this: * to check that criu works correctly if a kernel doesn't support userfaultfd. * to check compilation of the userfaultfd part in travis-ci. v2: remove UFFD from FEATURES_LIST Acked-by: Mike Rapoport <rppt@linux.vnet.ibm.com> Acked-by: Adrian Reber <areber@redhat.com> Cc: Mike Rapoport <rppt@linux.vnet.ibm.com> Cc: Adrian Reber <areber@redhat.com> Signed-off-by: Andrew Vagin <avagin@virtuozzo.com> Signed-off-by: Pavel Emelyanov <xemul@virtuozzo.com>
