Dear All,
I have gone through kref and am planning to implement then in my usb driver. please terminate my misconceptions if any by correcting the statements below.
In the call below: kref_init(&dev->kref); sets the refcount in the kref to 1.
kref_put(&dev->kref); increment the refcount.
kref_put(&dev->kref, mem_release ); What I understand is when the refcount falls back to '1', only then the mem_release() function will be called. Is it correct? I mean, when is the mem_release () called i.e. when the refcount is '0' or '1'.
Thanks & Regards, Mukund Jampala
