NAME

       blk_queue_ordered - does this queue support ordered writes

SYNOPSIS

       void blk_queue_ordered  (request_queue_t * q, int flag);

ARGUMENTS

       q      the request queue

       flag   see below

DESCRIPTION

       For  journalled  file  systems,  doing ordered writes on a commit block
       instead  of  explicitly  doing  wait_on_buffer  (which   is   bad   for
       performance)  can  be  a big win. Block drivers supporting this feature
       should call this function and indicate so.
