Subject: [patch 5/7] mm: unexport folio_memcg_{,un}lock
Date: Wed, 10 Nov 2021 20:32:43 -0800 [thread overview]
Message-ID: <20211111043243.8JTPHeFwZ%akpm@linux-foundation.org> (raw)
In-Reply-To: <20211110203204.37de96048c3279ab2da758a5@linux-foundation.org>
From: Christoph Hellwig <hch@lst.de>
Subject: mm: unexport folio_memcg_{,un}lock
Patch series "unexport memcg locking helpers".
Neither the old page-based nor the new folio-based memcg locking helpers
are used in modular code at all, so drop the exports.
This patch (of 2):
folio_memcg_{,un}lock are only used in built-in core mm code.
