hi,
if the partition is raw, can i give 1 for blocknr to write on first block. and for b_dev and b_rdev can i give the same value by the macro
MKDEV(8,16) where 8 is the major and 16 is the minor. i have declared a structure (struct block_device_operations block_bdops;)
and not defined as i am not using any bdops. is this ok to pass the structure while rigestering the block device or i need to define it?
