Kumar Kartikeya Dwivedi 23da464dd6 bpf: Allow specifying volatile type modifier for kptrs 
This is useful in particular to mark the pointer as volatile, so that
compiler treats each load and store to the field as a volatile access.
The alternative is having to define and use READ_ONCE and WRITE_ONCE in
the BPF program.
