From 6f67376318abea58589ebe6d69dffeabb6f6c26a Mon Sep 17 00:00:00 2001 From: Omar Sandoval Date: Mon, 16 Mar 2015 04:33:52 -0700 Subject: 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.
