Its filename was percpu-remove-unnecessary-initialization-in-pcpu_build_alloc_info.patch This patch was dropped because it was merged into the mm-stable branch of git://git.kernel.org/pub/scm/linux/kernel/git/akpm/mm ------------------------------------------------------ From: Sang-Heon Jeon Subject: percpu: remove unnecessary initialization in pcpu_build_alloc_info() Date: Wed, 2 Sep 2026 01:53:02 +0900 pcpu_build_alloc_info() initializes nr_groups to 1 and unconditionally sets it to the number of groups. Nothing uses it in between, so the initialization has no effect. Remove unnecessary initialization. No functional change.
