[patch 5/7] mm: unexport folio_memcg_{,un}lock

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: Christoph Hellwig <hch@xxxxxx>
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.
