This ioctl request reads from uffdio_continue structure written by
userspace which justifies _IOC_WRITE flag. It also writes back to that
structure which justifies _IOC_READ flag.
See NOTEs in include/uapi/asm-generic/ioctl.h for more information.
Fixes: f619147104c8 ("userfaultfd: add UFFDIO_CONTINUE ioctl")
