If anyone has any objections, please let me know. ------------------ From: Christoph Hellwig commit 16b8528d20607925899b1df93bfd8fbab98d267c upstream. We only want to steer the I/O completion towards a queue, but don't actually access any per-CPU data, so the raw_ version is fine to use and avoids the warnings when using smp_processor_id().
