From 2c97b7fc0d8c8661981beb9517da342ced3b3bc7 Mon Sep 17 00:00:00 2001 From: Johannes Weiner Date: Fri, 25 Jul 2008 19:46:01 -0700 Subject: mm: print swapcache page count in show_swap_cache_info() Every arch implements its own show_mem() function. Most of them share quite some code, some of them are completely identical. This series implements a generic version of this function and migrates almost all architectures to it. This patch: Most show_mem() implementations calculate the amount of pages within the swapcache every time. Move the output to a more appropriate place and use the anyway available total_swapcache_pages variable.
