[mahesh sobale <msobale007@xxxxxxxxx>]

HI,
 
     I am new to kernelnewbies. I am trying to print meta data in kernel space for superblock.
for that i have to fire ioctl and write char device driver(This part i know),
     
     But i don't know how create loop device and mount ext2 file system on that and then print 
superblock info.  

     Can anybody help on this.

Thanx.....
Mahesh.
