From c72df9f928efd5b17e84bdb7b8ec1be3b9c1ea9d Mon Sep 17 00:00:00 2001 From: Yongqiang Yang Date: Tue, 3 Jan 2012 23:43:39 -0500 Subject: ext4: pass verify_reserved_gdb() the number of group decriptors The 64bit resizer adds a flex group each time, so verify_reserved_gdb can not use s_groups_count directly, it should use the number of group decriptors before the added group.
