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.
