In previous patch series, Arthur sent fixes for the mthca IB driver. Other IB drivers like mlx4 also need this on Altix systems. Basically anything where the device DMAs some data into userspace and then DMAs a "completed" status to another buffer in userspace leads to a problem where the "completed" DMA might pass the actual data in the Altix fabric, which leads to the userspace process working with bogus data. - R. -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
