[PATCH 01/20] mm: print swapcache page count in show_swap_cache_info()

[Johannes Weiner <hannes@saeurebad.de>]

[-- Attachment #1: 0002-swapcache-page-count.patch --]
[-- Type: text/plain, Size: 834 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.
