26 Setting slice_idle to 0 will remove all the idling on queues/service tree
240 All cfq queues doing synchronous sequential IO go on to sync-idle tree.
241 On this tree we idle on each queue individually.
243 All synchronous non-sequential queues go on sync-noidle tree. Also any
244 request which are marked with REQ_NOIDLE go on this service tree. On this
245 tree we do not idle on individual queues instead idle on the whole group
246 of queues or the tree. So if there are 4 queues waiting for IO to dispatch
248 no more IO on this service tree.
250 All async writes go on async service tree. There is no idling on async
256 all the queues move to sync-noidle tree and only tree idle remains. This
257 tree idling provides isolation with buffered write queues on async tree.
263 A1. We only do tree idle (all queues on sync-noidle tree) on queues marked
284     Hence doing tree idling on threads using REQ_NOIDLE flag on requests
