Mike Rapoport cac673292b userfaultfd: shmem: allow registration of shared memory ranges ... Expand the userfaultfd_register/unregister routines to allow shared memory VMAs. Currently, there is no UFFDIO_ZEROPAGE and write-protection support for shared memory VMAs, which is reflected in ioctl methods supported by uffdio_register.
