Subject: [patch 01/22 -v2] Print current swapcache page count in show_swap_cache_info()
Date: Fri, 04 Apr 2008 13:51:38 +0200 [thread overview]
Message-ID: <20080404115230.720471887@skyscraper.fehenstaub.lan> (raw)
In-Reply-To: <20080404115137.397502419@skyscraper.fehenstaub.lan>
[-- Attachment #1: print-total_swapcache_pages-in-show_swap_cache_info.patch --]
[-- Type: text/plain, Size: 836 bytes --]
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.
