From 2158d3fd2769546cd9004eaeb776fee946155238 Mon Sep 17 00:00:00 2001 From: Phillip Lougher Date: Fri, 9 Mar 2012 02:27:49 +0000 Subject: [PATCH] Squashfs: fix f_pos check in get_dir_index_using_offset One off error in the f_pos check. If f_pos is 3 or less don't bother reading the index because we're at the start of the directory, and we obviously already know where that is on disk. This eliminates an unnecessary read.
