From c28e69d9332aab739920082a0a5677d861390824 Mon Sep 17 00:00:00 2001 From: Ryusuke Konishi Date: Sat, 24 Jul 2010 17:09:10 +0900 Subject: nilfs2: simplify nilfs_get_page function Implementation of nilfs_get_page() is a bit old as below: - A common read_mapping_page inline function is now available instead of its read_cache_page use. - wait_on_page_locked() use in the function is eliminable since read_cache_page function does the same thing through wait_on_page_read(). - PageUptodate() check is eliminable for the same reason. This renews nilfs_get_page() based on these points.
