opening a charcter device without using filp_open()

Hi all,

Is it possible to open a character device in kernel space without actually openning the device file? Because I don't wan to hold the usage count of a particular mount or dcache.

This is what I planned to do,

   struct file fake_devfile = {0};
   struct dentry fake_dentry = {0};
   struct inode fake_inode = {0};

   /* Link up fake file,dentry, inode */
   fake_file.f_dentry=&fake_dentry;
   fake_dentry.d_inode=&fake_inode;

Then I will call the f_op of the character device directly, please give advice. Thanks.

regards,
David Chow
