From f5c754d63d069dabe2afc6f248188b5148e08687 Mon Sep 17 00:00:00 2001 From: Colin Ian King Date: Thu, 5 Apr 2018 16:25:05 -0700 Subject: [PATCH] mm/swap_state.c: make bool enable_vma_readahead and swap_vma_readahead() static The bool enable_vma_readahead and swap_vma_readahead() are local to the source and do not need to be in global scope, so make them static. Cleans up sparse warnings: mm/swap_state.c:41:6: warning: symbol 'enable_vma_readahead' was not declared. Should it be static? mm/swap_state.c:742:13: warning: symbol 'swap_vma_readahead' was not declared. Should it be static?
