nilfs2: record used amount of each checkpoint in checkpoint list
This records the number of used blocks per checkpoint in each checkpoint entry of cpfile. Even though userland tools can get the block count via nilfs_get_cpinfo ioctl, it was not updated by the nilfs2 kernel code. This fixes the issue and makes it available for userland tools to calculate used amount per checkpoint. Signed-off-by: Ryusuke Konishi <konishi.ryusuke@lab.ntt.co.jp> Cc: Jiro SEKIBA <jir@unicus.jp>
