async_pq_val: fix DMA memory leak

2017-02-23T03:54:09Z

commit c84750906b4818d4929fbf73a4ae6c113b94f52b upstream. Add missing dmaengine_unmap_put(), so we don't OOM during RAID6 sync.

async_tx: use GFP_NOWAIT rather than GFP_IO

2016-01-25T10:44:04Z

commit b02bab6b0f928d49dbfb03e1e4e9dd43647623d7 upstream. These async_XX functions are called from md/raid5 in an atomic section, between get_cpu() and put_cpu(), so they must not sleep. So use GFP_NOWAIT rather than GFP_IO. Dan Williams writes: Longer term async_tx needs to be merged into md directly as we can allocate this unmap data statically per-stripe rather than per request.

Merge commit 'dmaengine-3.13-v2' of git://git.kernel.org/pub/scm/linux/kernel/git/djbw/dmaengine

2013-11-16T06:32:36Z

Pull dmaengine changes from Dan 1/ Bartlomiej and Dan finalized a rework of the dma address unmap implementation. 2/ In the course of testing 1/ a collection of enhancements to dmatest fell out. Notably basic performance statistics, and fixed / enhanced test control through new module parameters 'run', 'wait', 'noverify', and 'verbose'. Thanks to Andriy and Linus for their review. 3/ Testing the raid related corner cases of 1/ triggered bugs in the recently added 16-source operation support in the ioatdma driver. 4/ Some minor fixes / cleanups to mv_xor and ioatdma.

raid6test: add new corner case for ioatdma driver

2013-11-14T19:04:42Z

With 24 disks and an ioatdma instance with 16 source support there is a corner case where the driver needs to be careful to account for the number of implied sources in the continuation case. Also bump the default case to test more than 16 sources now that it triggers different paths in offload drivers. Cc: Dave Jiang Acked-by: Dave Jiang Signed-off-by: Dan Williams
