Message-ID: <4f5ac26d.cUNt6jDcU1/Q0PqV%phillip@lougher.demon.co.uk> Date: Sat, 10 Mar 2012 02:54:37 +0000 From: Phillip Lougher <phillip@...gher.demon.co.uk> To: linux-kernel@...r.kernel.org, linux-fsdevel@...r.kernel.org Subject: [PATCH 5/6] 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.
