Subject: [PATCH] Btrfs-progs: check all slots in leaves
Date: Tue, 30 Sep 2014 16:56:05 -0400 [thread overview]
Message-ID: <1412110565-7889-1-git-send-email-jbacik@fb.com> (raw)
There's an off by one error in btrfs_check_leaf, we should be going to nritems -
1, not nritems - 2, we were missing problems with items in the very last slot.
Thanks,
