[RFC 1/2] ext4 resize: Mark the added group with EXT4_BG_INODE_ZEROED flag

[<Solofo.Ramangalahy@bull.net>]

[-- Attachment #1: SR-ext4-resize-mark-new-group-EXT_BG_INODE_ZEROED.patch --]
[-- Type: text/plain, Size: 896 bytes --]

The inode table has been zeroed in setup_new_group_blocks().
Mark it as such in ext4_group_add().

As a side note, online resize and inode zeroing are "dual".

In order to obtain a filesystem with faster formating times one can
do:
. either format a smaller fs and then resize it,
. or format the fs with lazy_itable_init
