Revision b02bab6b0f928d49dbfb03e1e4e9dd43647623d7 authored by NeilBrown on 07 January 2016, 00:02:34 UTC, committed by Vinod Koul on 07 January 2016, 05:36:18 UTC
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. Fixed: 7476bd79fc01 ("async_pq: convert to dmaengine_unmap_data") Cc: stable@vger.kernel.org (v3.13+) Reported-and-tested-by: Stanislav Samsonov <slava@annapurnalabs.com> Acked-by: Dan Williams <dan.j.williams@intel.com> Signed-off-by: NeilBrown <neilb@suse.com> Signed-off-by: Vinod Koul <vinod.koul@intel.com>
