From 49a2f1e3f231f6b2ccfc8192f4c395de7fa910a1 Mon Sep 17 00:00:00 2001 From: Tejun Heo Date: Tue, 14 May 2013 13:52:34 -0700 Subject: [PATCH] blk-throttle: add throtl_grp->service_queue Currently, there's single service_queue per queue - throtl_data->service_queue. All active throtl_grp's are queued on the queue and dispatched according to their limits. To support hierarchy, this will be expanded such that active throtl_grp's form a tree anchored at throtl_data->service_queue and chained through each intermediate throtl_grp's service_queue. This patch adds throtl_grp->service_queue to prepare for hierarchy support. The initialization function - throtl_service_queue_init() - is added and replaces the macro initializer. The newly added tg->service_queue isn't used yet. Following patches will do. Signed-off-by: Tejun Heo Acked-by: Vivek Goyal --- Reading git-format-patch failed
