Ensure the MR's PBL array never occupies the last 8 bytes of a page. This eliminates random "Local Protection Error" flushes when SLUB debugging is enabled. Fixes: 1b2cd0fc673c ('IB/mlx4: Support the new memory registration API')Can't the driver advertize smaller quantity for what's occupies later those last eight bytes (255 or 511 of attr XX instead of 256 or 512)?
Not sure I understand your question. Are you suggesting that the driver would expose that it's capable of 256 pages per MR? -- To unsubscribe from this list: send the line "unsubscribe linux-nfs" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
