By doing this change, we remove one of the last in-kernel user that was
storing the result of debugfs_create_bool(), so that api can be cleaned
up.
Question not about this specific change, but the general concept
of keeping (or not keeping) dentry pointers. In the ath drivers,
as well as in an out-of-tree driver for Android, we keep a
debugfs dentry pointer to use as a param to relay_open().
Will we still be able to have a dentry pointer for this purpose?
Or better, is there a recommended way to get a dentry pointer
NOT associated with debugfs at all (which would be ideal for
Android where debugfs is disabled).
Thanks,
Jeff
