[PATCH v2 0/1] TCPM logbuffer wraparound

[Badhri Jagan Sridharan <badhri@google.com>]

This is a follow up on a previous discussion:
https://lore.kernel.org/lkml/20230410073134.488762-1-badhri@google.com/.

With this change, TCPM log buffer will now wrap around when full and
will not self-clear upon being read (dumped). A Kconfig option and a
corresponding debugfs file node are introduced to allow opt-in back to
the previous, non-wrapping, self-clearing behavior if required.
This is an interim step while TCPM logging infrastructure is migrated
to the standard event trace system.
