int major;

static int
char_open(
               struct inode *inode,    /*What Inode is this ?*/

The struct inode corresponding to the file being opened. In your case, 
/dev/trial2.

               struct file * file              /*What File is this ? */

The struct file corresponding to the file descriptor given to you whn 
you called open() on this device file.

               ) {
