[QUESTION] Getting block bitmap

[Sayan Ghosh <sgdgp.2014@xxxxxxxxx>]

Hello,

bh = ext4_read_block_bitmap(sb,block_group);

This function return the buffer head for the block/page with the block bitmap

char *block_bmap = bh->b_data;

Doing this does not give the block bitmap string

What is the process to get the block bitmap in string or array form?

Regards,
Sayan
