From aca8bf323edd31ad462dc98c107c23a5c6022ca2 Mon Sep 17 00:00:00 2001 From: Minchan Kim Date: Tue, 16 Jun 2009 15:33:02 -0700 Subject: [PATCH] mm: remove file argument from swap_readpage() The file argument resulted from address_space's readpage long time ago. We don't use it any more. Let's remove unnecessary argement.
