From 17b429239dac374b62d827b424dae35f9df1ef77 Mon Sep 17 00:00:00 2001 From: Bradley Morgan Date: Tue, 15 Sep 2026 18:06:23 +0000 Subject: [PATCH] taskstats: drop the unused CPU_DONT_CARE enum member CPU_DONT_CARE was added by the original listener cpumask code in 2006 (f9fd8914c1ac) and has never had a single user, not even in the commit that introduced it. It survived every refactor of the listener path since, including the recent handler folds. Kill it, twenty years is enough.
