From acd02443a952b1f5412d35d03f081ad48bae34d7 Mon Sep 17 00:00:00 2001 From: John Baldwin Date: Mon, 8 Dec 2025 11:15:52 -0500 Subject: [PATCH] proc0_post: Clear relevant thread stats directly rufetch() has several other effects besides clearing these per-thread stats most of which are explicitly discarded by the subsequent calls to ruxreset(). Just clear the relevant stats directly instead.
