From 05dc4a9fc8b36d4c99d76bbc02aa9ec0132de4c2 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Thomas=20Wei=C3=9Fschuh?= Date: Wed, 7 Jan 2026 11:39:24 +0100 Subject: hrtimer: Fix softirq base check in update_needs_ipi() MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit The 'clockid' field is not the correct way to check for a softirq base. Fix the check to correctly compare the base type instead of the clockid.
