Its filename was percpu-fix-wrong-chunk-hints-update.patch This patch was dropped because an updated version will be issued ------------------------------------------------------ From: Joonwon Kang Subject: percpu: fix wrong chunk hints update Date: Wed, 13 May 2026 08:51:13 +0000 Chunk end offset was set to a block end offset, which could prevent chunk hints from being updated correctly. It was observed that the chunk free size gets minus or shorter than the actual free size due to this. This commit fixes it.
