Subject: [PATCH 7/8] mm/percpu: remove unused PERCPU_DYNAMIC_EARLY_SLOTS
Date: Mon, 24 Oct 2022 16:14:34 +0800	[thread overview]
Message-ID: <20221024081435.204970-8-bhe@redhat.com> (raw)
In-Reply-To: <20221024081435.204970-1-bhe@redhat.com>

Since commit 40064aeca35c ("percpu: replace area map allocator with
bitmap"), there's no place to use PERCPU_DYNAMIC_EARLY_SLOTS. So
clean it up.
