perf tools: Don't warn about out of order event if write_backward is used (2016-01-25 09:49:15 +0000)
----------------------------------------------------------------
perf improvements:

Use feature-dump results for build-test
- BPF related improvements:
Enable indices syntax to support init BPF maps
Support BPF output events support
- perf/core:
Add write_backward attribute bit to support reading from
overwrite ring buffer
- perf record improvements:
Enable perf record dump different output
Support reading from overwrite ring buffer based on write_backward
attribute
