tracing: Add snapshot feature to instances ...
Add the "snapshot" file to the the multi-buffer instances.
cd /sys/kernel/debug/tracing/instances
mkdir foo
ls foo
buffer_size_kb buffer_total_size_kb events free_buffer set_event
snapshot trace trace_clock trace_marker trace_options trace_pipe
tracing_on
cat foo/snapshot
# tracer: nop
#
#
# * Snapshot is freed *
#
# Snapshot commands:
# echo 0 > snapshot : Clears and frees snapshot buffer
# echo 1 > snapshot : Allocates snapshot buffer, if not already allocated.
# Takes a snapshot of the main buffer.
# echo 2 > snapshot : Clears snapshot buffer (but does not allocate)
# (Doesn't have to be '2' works with any number that
# is not a '0' or '1')
