Cover letter [PATCH v3 0/5] trace-cmd: Improve multi-instance support
NOTE: The previous two versions of this patch set were distributed off-list.
v3 changes:
* Improved clarification of options in documentation of trace-cmd reset and added examples.
v2 changes:
* Rebased this patch series on Steve's simplification of first_instance logic.
Improve the completeness and consistency of support for multiple buffer instances in the extract, snapshot, stat, start, stop, reset, and restart sub-commands.
For the commands that lacked it, added support for -B and -t options, consistent with the existing behavior of stop, reset, and restart. That is, including a -B instance-name option will cause these commands to exclude the top buffer instance unless -t is also provided.
Exception: trace-cmd start retains its existing behavior regarding the top instance, consistent with trace-cmd record.
For all of these sub-commands except start, add a new -a option, which causes it to operate on all existing instances. As with -B, -a will exclude the top instance unless -t is also given.
Updated documentation accordingly.
