From 090d2b185d8680fc26a2eaf4245d4171dcf4baf1 Mon Sep 17 00:00:00 2001 From: Pekka Enberg Date: Fri, 23 Jun 2006 02:05:08 -0700 Subject: [PATCH] read_mapping_page for address space Add read_mapping_page() which is used for callers that pass mapping->a_ops->readpage as the filler for read_cache_page. This removes some duplication from filesystem code.
