fuse: Fix return value from fuse_get_user_pages()
fuse_get_user_pages() should return error or 0. Otherwise fuse_direct_io read will not return 0 to indicate that read has completed. Fixes: 742f992708df ("fuse: return patrial success from fuse_direct_io()") Signed-off-by: Ashish Samant <ashish.samant@oracle.com> Signed-off-by: Seth Forshee <seth.forshee@canonical.com> Signed-off-by: Miklos Szeredi <mszeredi@redhat.com>
