To get started with the code I would suggest the following order: [md-accel PATCH 01/19] dmaengine: refactor dmaengine around dma_async_tx_descriptor [md-accel PATCH 04/19] async_tx: add the async_tx api [md-accel PATCH 07/19] md: raid5_run_ops - run stripe operations outside sh->lock [md-accel PATCH 16/19] dmaengine: driver for the iop32x, iop33x, and iop13xx raid engines The patch set can be broken down into three main categories: 1/ API (async_tx: patches 1 - 4) 2/ implementation (md changes: patches 5 - 15) 3/ driver (iop-adma: patches 16 - 19) I have worked with Neil to get approval of the category 2 changes. However for the category 1 and 3 changes there was no obvious merge-path/maintainer to work through. I have thus far extrapolated Neil's comments about 2 out to 1 and 3, Jeff gave some direction on a early revision about the scalability of the API, and the patch set has picked up various fixes and suggestions from being in -mm for a few releases. Please help me ensure that this code is ready for Linus to pull for 2.6.23. git://lost.foo-projects.org/~dwillia2/git/iop md-accel-linus Dan Williams (19): dmaengine: refactor dmaengine around dma_async_tx_descriptor dmaengine: make clients responsible for managing channels xor: make 'xor_blocks' a library routine for use with async_tx async_tx: add the async_tx api raid5: refactor handle_stripe5 and handle_stripe6 (v2) raid5: replace custom debug PRINTKs with standard pr_debug md: raid5_run_ops - run stripe operations outside sh->lock md: common infrastructure for running operations with raid5_run_ops md: handle_stripe5 - add request/completion logic for async write ops md: handle_stripe5 - add request/completion logic for async compute ops md: handle_stripe5 - add request/completion logic for async check ops md: handle_stripe5 - add request/completion logic for async read ops md: handle_stripe5 - add request/completion logic for async expand ops md: handle_stripe5 - request io processing in raid5_run_ops md: remove raid5 compute_block and compute_parity5 dmaengine: driver for the iop32x, iop33x, and iop13xx raid engines iop13xx: surface the iop13xx adma units to the iop-adma driver iop3xx: surface the iop3xx DMA and AAU units to the iop-adma driver ARM: Add drivers/dma to arch/arm/Kconfig Administrivia: This patch set contains three new patches compared to the previous release they are: [md-accel PATCH 03/19] xor: make 'xor_blocks' a library routine for use with async_tx [md-accel PATCH 05/19] raid5: refactor handle_stripe5 and handle_stripe6 (v2) [md-accel PATCH 06/19] raid5: replace custom debug PRINTKs with standard pr_debug net/core/dev.c is touched by the following: [md-accel PATCH 02/19] dmaengine: make clients responsible for managing channels - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
