Subject: [PATCH 20/31] blk-throttle: add throtl_service_queue->parent_sq
Date: Wed, 1 May 2013 17:39:38 -0700 [thread overview]
Message-ID: <1367455189-6957-21-git-send-email-tj@kernel.org> (raw)
In-Reply-To: <1367455189-6957-1-git-send-email-tj@kernel.org>
To prepare for hierarchy support, this patch adds
throtl_service_queue->service_sq which points to the arent
service_queue. Currently, for all service_queues embedded in
throtl_grps, it points to throtl_data->service_queue. As
throtl_data->service_queue doesn't have a parent its parent_sq is set
to NULL.
There are a number of functions which take both throtl_grp *tg and
throtl_service_queue *parent_sq. With this patch, the parent
service_queue can be determined from @tg and the @parent_sq arguments
are removed.
This patch doesn't make any behavior differences.
