-Snapshot
---------
-CONFIG_TRACER_SNAPSHOT makes a generic snapshot feature
-available to all non latency tracers. (Latency tracers which
-record max latency, such as "irqsoff" or "wakeup", can't use
-this feature, since those are already using the snapshot
-mechanism internally.)
-
-Snapshot preserves a current trace buffer at a particular point
-in time without stopping tracing. Ftrace swaps the current
-buffer with a spare buffer, and tracing continues in the new
-current (=previous spare) buffer.
-
-The following debugfs files in "tracing" are related to this
-feature:

-  snapshot:
-
-	This is used to take a snapshot and to read the output
-	of the snapshot. Echo 1 into this file to allocate a
-	spare buffer and to take a snapshot (swap), then read
-	the snapshot from this file in the same format as
-	"trace" (described above in the section "The File
-	System"). Both reads snapshot and tracing are executable
-	in parallel. When the spare buffer is allocated, echoing
-	0 frees it, and echoing else (positive) values clear the
-	snapshot contents.
-	More details are shown in the table below.
