From 519a286175b6422e13694ebb73aefee0b5749443 Mon Sep 17 00:00:00 2001 From: Dan Carpenter Date: Wed, 10 Dec 2014 15:41:37 -0800 Subject: [PATCH] ocfs2: fix an off-by-one BUG_ON() statement The ->si_slots[] array is allocated in ocfs2_init_slot_info() it has "->max_slots" number of elements so this test should be >= instead of >. Static checker work. Compile tested only.
