| |
Ingo,
I rebased again (using ftrace-2 now) and made some minor clean ups to the patches, as well as added several new ones.
The last patch of the series adds a benchmark/tester for the ring buffer. It creates a producer and consumer and measures the time and number of entries recorded. It prints out the results via pr_info every 10 seconds.
Please pull the latest tip/tracing/ftrace-2 tree, which can be found at:
