Staging: lttng: remove from the drivers/staging/ tree 



The "proper" way to do this is to work with the existing in-kernel
tracing subsystem and work to get the missing features that are in lttng
into those subsystems.

config LTTNG

	tristate "LTTng kernel tracer"

	depends on TRACEPOINTS

	help

	  The LTTng 2.0 Tracer Toolchain allows integrated kernel and

	  user-space tracing from a single user interface: the "lttng"

	  command. See http://lttng.org website for the "lttng-tools"

	  user-space tracer control tools package and the "babeltrace"

	  package for conversion of trace data to a human-readable

	  format.



	  LTTng features:

	  - System-wide tracing across kernel, libraries and

	    applications,

	  - Tracepoints, detailed syscall tracing (fast strace replacement),

	    Function tracer, CPU Performance Monitoring Unit (PMU) counters

	    and kprobes support,

	  - Have the ability to attach "context" information to events in the

	    trace (e.g. any PMU counter, pid, ppid, tid, comm name, etc). All

	    the extra information fields to be collected with events are

	    optional, specified on a per-tracing-session basis (except for

	    timestamp and event id, which are mandatory).

	  - Precise and fast clock sources with near cycle-level

	    timestamps,

	  - Efficient trace data transport:

	    - Compact Binary format with CTF,

	    - Per-core buffers ensures scalability,

	    - Fast-paths in caller context, amortized synchronization,

	    - Zero-copy using splice and mmap system calls, over disk,

	      network or consumed in-place,

	  - Multiple concurrent tracing sessions are supported,

	  - Designed to meet hard real-time constraints,

	  - Supports live streaming of the trace data,

	  - Produces CTF (Common Trace Format) natively (see

	    http://www.efficios.com/ctf).
