From d2849fb294d92d6eee0a811c688f1ecb39d26800 Mon Sep 17 00:00:00 2001 From: Jan Kara Date: Wed, 19 Dec 2007 15:24:09 +0100 Subject: [PATCH] ocfs2: Safer read_inline_data() In ocfs2_read_inline_data() we should store file size in loff_t. Although the file size should fit in 32 bits we cannot be sure in case filesystem is corrupted.
