linux-stable.git/tools/testing/selftests/kvm/include/userfaultfd_util.h, branch linux-6.6.y Linux kernel stable tree KVM: selftests: Add a userfaultfd library 2022-11-10T19:10:27+00:00 Ricardo Koller ricarkol@google.com 2022-10-17T19:58:21+00:00 a93871d0ea9fd59fb5eb783619334183d7f07f51 Move the generic userfaultfd code out of demand_paging_test.c into a common library, userfaultfd_util. This library consists of a setup and a stop function. The setup function starts a thread for handling page faults using the handler callback function. This setup returns a uffd_desc object which is then used in the stop function (to wait and destroy the threads).
