Merge branch 'work.splice_read' of git://git.kernel.org/pub/scm/linux/kernel/git/viro/vfs
Pull splice fixups from Al Viro: "A couple of fixups for interaction of pipe-backed iov_iter with O_DIRECT reads + constification of a couple of primitives in uio.h missed by previous rounds. Kudos to davej - his fuzzing has caught those bugs" * 'work.splice_read' of git://git.kernel.org/pub/scm/linux/kernel/git/viro/vfs: [btrfs] fix check_direct_IO() for non-iovec iterators constify iov_iter_count() and iter_is_iovec() fix ITER_PIPE interaction with direct_IO
