Yep, back when we integrated the code upstream, we were testing on IA64 too - where the system page size was 16KB but for some reasons SGs provided by the block layer were many times NON FMR aligned if you worked with 16KB FMR chunks. I would recommend to test on PPC64 and if possible on IA64 before/after removing the usage of 4k segments. -- To unsubscribe from this list: send the line "unsubscribe linux-rdma" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
