This patch-set has the Dan Williams' comments (Dec, 17) addressed with the following exception: - I still think that using 'enum dma_ctrl_flags' for PQ-specific operations is better than introducing another group of flags and enhance the device_prep_dma_pq()/device_prep_dma_pqzero_sum() with one more parameter. If unchanged 'enum dma_ctrl_flags' will be a criteria of acceptance, please let me know - I'll re-implement this exactly as Dan suggested. Fearing to look like a spammer, I post only those patches, which had been affected by the changes intended to address Dan's comments. These are the following five: 0002-async_tx-add-support-for-asynchronous-GF-multiplica.patch 0003-async_tx-add-support-for-asynchronous-RAID6-recover.patch 0004-md-run-RAID-6-stripe-operations-outside-the-lock.patch 0008-md-asynchronous-handle_parity_check6.patch 0011-ppc440spe-adma-ADMA-driver-for-the-PPC440SP-e-syst.patch As regarding the other six patches of asynchronous RAID-6 support patchset: 0001-async_tx-don-t-use-src_list-argument-of-async_xor.patch 0005-md-common-schedule_reconstruction-for-raid5-6.patch 0006-md-change-handle_stripe_fill6-to-work-in-asynchrono.patch 0007-md-rewrite-handle_stripe_dirtying6-in-asynchronous.patch 0009-md-change-handle_stripe6-to-work-asynchronously.patch 0010-md-remove-unused-functions.patch they are the same as in my 09 Dec 2008 post: https://kerneltrap.org/mailarchive/linux-raid/2008/12/8/4367574 and are waiting for your comments.
