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

[Eduardo Mucelli Rezende Oliveira]

Hi Masami,

Here are four more fixes for ftrace2bconf.sh, based on bootconfig/fixes.
They address settings that change or fail to restore after export:

- Event filters containing punctuation are quoted as one bootconfig value.
- Generic trigger counts are written in the syntax accepted by tracefs.
- Histogram variable tracking starts fresh for each tracing instance.
- Paused histograms keep their paused state when restored.

The base includes the trigger-filter and underscore fixes you picked up.
The new sed expression also uses POSIX syntax, following your feedback.

I tested each fix and the full series in temporary tracefs instances on
my Ubuntu machine, running kernel 7.0.0-38-generic, with recording
disabled. The patch emails include the individual reproduction details.
The fixture checks also cover each step of the series.

Feedback is welcome.

Thanks,
Eduardo
