iocb: delay evaluation of IS_SYNC(...) until we want to check IOCB_DSYNC
New helper to be used instead of direct checks for IOCB_DSYNC: iocb_is_dsync(iocb). Checks converted, which allows to avoid the IS_SYNC(iocb->ki_filp->f_mapping->host) part (4 cache lines) from iocb_flags() - it's checked in iocb_is_dsync() instead Reviewed-by: Christian Brauner (Microsoft) <brauner@kernel.org> Signed-off-by: Al Viro <viro@zeniv.linux.org.uk>
