Subject: [PATCH] mm: Remove the BOUNCE config option
Date: Mon, 13 Oct 2025 17:56:20 +0800 [thread overview]
Message-ID: <20251013095620.1111061-1-chenhuacai@loongson.cn> (raw)
Commit eeadd68e2a5f6bfe0bf10 ("block: remove bounce buffering support")
remove block/bounce.c but left the BOUNCE config option. Now this option
has no users, so remove it.
