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

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



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
