Subject: mm: unexport folio_memcg_{,un}lock
X-Git-Url: https://www.infradead.org/git/?a=commitdiff_plain;h=eaa5f1ad6cc2988c8fa012fa4b8ee25cc96080ea;p=users%2Fjedix%2Flinux-maple.git

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.
