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.
