Please DO NOT SEND new versions of a patch or patch series as a reply to
the old one. It makes it extremely difficult for maintainers to manage the
replies and patches.

A new version should ALWAYS start a new email thread!

Hi Masami, Steven, all,

This is v3 of the ftrace stackmap series. It addresses the Sashiko
review on v2 [1] that Masami pointed out.

[1] https://sashiko.dev/#/patchset/20260522104017.1668638-1-lipengfei28%40xiaomi.com

The series adds stack trace deduplication to ftrace. When the
stacktrace option is enabled, the ring buffer stores a 4-byte
stack_id instead of a full kernel stack trace, while the full
stacks are exported via tracefs.

Rebased onto v7.1-rc5 (e8c2f9fdadee) before sending.

Changes since v2
================

Then you can use lore to add a link to the old version via the Message-ID
of the old version. You can have the above as:
