direct_IO: use iov_iter_rw() instead of rw everywhere
The rw parameter to direct_IO is redundant with iov_iter->type, and treated slightly differently just about everywhere it's used: some users do rw & WRITE, and others do rw == WRITE where they should be doing a bitwise check. Simplify this with the new iov_iter_rw() helper, which always returns either READ or WRITE. Signed-off-by: Omar Sandoval <osandov@osandov.com> Signed-off-by: Al Viro <viro@zeniv.linux.org.uk>
