[PATCH v2] tools/rtla: Fix --dump-tasks usage in timerlat
Posted by Costa Shulyupin 2 months ago
Fix --dump-task to --dump-tasks in timerlat_hist usage string
and getopt_long table for consistency with timerlat_top.

Add missing --dump-tasks to timerlat_top usage synopsis.

Please also add the link to v1 next time when sending a v2, it makes
it easier to check what is being addressed in the v2.
