From ff1be9ad61e3e17ba83702d8ed0b534e5b8ee15c Mon Sep 17 00:00:00 2001 From: OGAWA Hirofumi Date: Sun, 20 May 2007 23:39:40 +0900 Subject: [PATCH] Fix "fs: convert core functions to zero_user_page" The bug was introduced by 01f2705daf5a36208e69d7cf95db9c330f843af6. It misses to convert the first argument, it should be "new_page". This became a cause of fatfs corruption.
