opening a charcter device without using filp_open()

[David Chow]

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,
