Lars Ellenberg e5f891b223 drbd: gather detailed timing statistics for drbd_requests
Record (in jiffies) how much time a request spends in which stages.
Followup commits will use and present this additional timing information
so we can better locate and tackle the root causes of latency spikes,
or present the backlog for asynchronous replication.
