The patch titled Subject: mm: unexport folio_memcg_{,un}lock has been removed from the -mm tree. Its filename was mm-unexport-folio_memcg_unlock.patch This patch was dropped because it was merged into mainline or a subsystem tree ------------------------------------------------------ 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.
