[PATCH 0/2] tools/bootconfig: Preserve filters when resetting and applying tracing

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

Hi Masami,

Here are two more fixes for the bootconfig tracing scripts. They address
resetting existing histograms and applying saved filter strings. The
patches can be applied independently.

The first patch fixes histogram removal when a filter contains brackets
or repeated spaces. A failed removal can leave a variable provider
installed after reset, including a case where the helper returns success.
It uses separate sed expressions for [active] and [paused], following
your portability feedback.

The second patch keeps quoted strings intact when applying a bootconfig.
Currently, repeated spaces can be collapsed and literal wildcard
characters can expand to filenames, changing the filter being installed.

Both were tested in temporary tracefs instances on my Ubuntu machine,
running kernel 7.0.0-38-generic, with recording disabled. The individual
patch emails include the reproduction details.

Feedback is welcome.

Thanks,
Eduardo
