From 22a94d44bd6876a90630338229da6c0436d46593 Mon Sep 17 00:00:00 2001 From: Josef Bacik Date: Wed, 16 Mar 2011 16:47:17 -0400 Subject: Btrfs: add checks to verify dir items are correct We need to make sure the dir items we get are valid dir items. So any time we try and read one check it with verify_dir_item, which will do various sanity checks to make sure it looks sane.
