local_dev=container_of(inode->i_cdev, struct scull_dev,cdev1);
in above function, i don’t know how container_of() give the minor number and also how assign global device to local device.

it dosnt give minor no. it returns the pointer which contains the cdev structure if cdev is the last (3rd) argument
