From 83b7c996dc859c7b53f94d46ee5c5929cc0399e2 Mon Sep 17 00:00:00 2001 From: OGAWA Hirofumi Date: Sun, 8 Jan 2006 01:02:09 -0800 Subject: [PATCH] [PATCH] fat: use sb_find_get_block() instead of sb_getblk() We don't need to allocate buffer for checking the buffer is uptodate. This use sb_find_get_block() instead, and if it returns NULL it's not uptodate.
