[PATCH v2 0/4] fuse: Improve ftraces, per-cpu req unique and code dup removal

[Bernd Schubert <bschubert@ddn.com>]

This series is mainly about improved ftraces to determine
latencies between queues and also to be able to create
latency histograms - the request unique was missing in
trace_fuse_request_send so far.
Some preparation patches are added before.

Scripts to enabled tracing and to get histograms are here
