I finished my review of this series. Looks good! I'm hoping that v8 will be the final one. Thanks Tzvetomir, -- Steve

Introduce the next version of the trace-cmd trace file - 7. Major changes since version 6 is more flexible extendable structure of the file, based on independent sections. v7 changes: - Rebased on top of the latest master. - Introduced new metadata strings section. - Use 8 bytes for section size. v6 changes: - Rebased on top of the latest master. - On trace file v7 close, write any unsaved options in the file - as a last section. - Removed the patch "Do not write CPUs with empty trace data" from the patch set. Empty CPUs are written in v7 trace files, the same way as in v6. v5 changes: - Rebased on top of the latest master. v4 changes: - Rebased on top of the latest master. v3 changes: - Fixed issues of split and convert commands with some corner cases. v2 changes: - Code cleanups.
