Looking at your fix and not even pretending to know what's going on with that percpu sequence counting, I can't help but wonder why do you wanna do: seq = *raw_cpu_ptr(&discard_pa_seq); instead of simply doing: seq = this_cpu_read(discard_pa_seq); ? -- Regards/Gruss, Boris. https://people.kernel.org/tglx/notes-about-netiquette
