Hi,

I come across this code: http://elixir.free-electrons.com/linux/latest/source/drivers/scsi/scsi_netli...

other fields such as .cbmutex, .bind, etc are not initialized.

Since the object =cfg= is of automatic storage, I wonder how the kernel tells if a field is initialized or its value is just some random bits on the stack?

The fields are initialized to zero. It's a C specification requirement.

Hope this helps,
