Hello, I am trying to understand the block allocation in ext4 file sytem, I have gone through all basic theory and browsing code to do it. I am writing a module in which i got ext4 on disk inode, now according to theory first 12 bytes of i_block points to ext4_extent_header, so can i use this array of i_block[EXT4_N_BLOCKS]. Means how to fill objects of struct ext4_extent_header (using first 12 byte of i_block) and struct ext4_extent (using reminder bytes of i_block). -- Regards, Akshay Nehe. -- To unsubscribe from this list: send the line "unsubscribe linux-ext4" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
