2012-01-03ext4: pass verify_reserved_gdb() the number of group decriptorsYongqiang Yang
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. Signed-off-by: Yongqiang Yang <xiaoqiangnk@gmail.com> Signed-off-by: "Theodore Ts'o" <tytso@mit.edu>
2012-01-03ext4: add a function which updates the super block during online resizingYongqiang Yang
This patch adds a function named ext4_update_super() which updates super block so the newly created block groups are visible to the file system. This code is copied from ext4_group_add(). The function will be used by new resize implementation. Signed-off-by: Yongqiang Yang <xiaoqiangnk@gmail.com> Signed-off-by: "Theodore Ts'o" <tytso@mit.edu>

2012-01-03ext4: add a function which extends a group without checking parametersYongqiang Yang
