I meant that the Sashiko's email header parser may failed to parse the thread correctly. - The patches in this series are listed separately. https://sashiko.dev/#/?list=org.kernel.vger.linux-trace-kernel - The cover mail also listed and the page has "Thread" list but it only has replies to the cover mail. No other patches. https://sashiko.dev/#/patchset/20260522170857.263969486%40kernel.org - v18 seems correctly parsed, which has "In-Reply-To:" tag in the mail header. https://sashiko.dev/#/patchset/177701351903.2223789.17087009302463188638.stgit%40mhiramat.tok.corp.google.com So I guess Sashiko's email header parser does not correctly handle the "References:" tag for recognizing thread.
