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
