[PATCH v2 0/4] tools/bootconfig: Preserve tracing settings during export

[Eduardo Mucelli Rezende Oliveira <edumucelli@gmail.com>]

Hi Masami,

Thanks for the review. I've updated the event-filter patch to use the
explicit delimiter pattern you suggested. It now warns and skips filters
that contain delimiters and both quote types, since bootconfig cannot
represent them. The other three patches are unchanged.

Changes in v2:
- Patch 1: use explicit escapes in *[,\;\#\}]* for the delimiter check.
  The semicolon also needs escaping for the shell to parse the pattern.
- Patch 1: detect both quote types, warn on stderr and skip the filter.
- Patches 2-4: no changes.

The series keeps event filters, generic trigger counts, histogram
variable ordering and paused histogram state during export. It is still
based on bootconfig/fixes, including the two fixes you picked up earlier.

I retested the filter change in a temporary tracefs instance on my Ubuntu
machine, running kernel 7.0.0-38-generic, with recording disabled. I also
checked the mixed-quote cases against real tracefs filters and added
regression checks for both quote orders and all four delimiters. The
fixture checks cover each fix and the full series.

Feedback is welcome.

Thanks,
Eduardo
