revision 2.23
date: 2013/08/01 11:53:49; author: rahul; state: Exp; lines: +7 -6
done with proc
able to creat pages.

revision 2.22
date: 2013/08/01 11:00:22; author: rahul; state: Exp; lines: +78 -35
done with ioctl command
created scull_ioctl function.
able to change the quantum size.
—————————-
revision 2.21
date: 2013/07/26 11:08:11; author: rahul; state: Exp; lines: +108 -11
implemented spin_lock()
implemented completion()
but to implement syncro between writes of two diffrent applications & reads of two diffrent applications, we have to use semaphore between application.

faced problem with trim function again.
previous ligic was not correct.
used data_size which was declared in struct sculldev.
working fine
