The file descriptor concept is the way it works in the rest of the
kernel. It works for numerous drivers and subsystems (KVM, VFIO, UIO,
...), when you close a file descriptor handed out from any of those
drivers (already in the kernel) all related resources will be freed. I
don't see a reason why HSA drivers should break these expectations and
be different.
