[PATCH] dmaengine: ioat: Allocate correct size for descriptor chunk

2020-09-22 Thread Logan Gunthorpe
dma_alloc_coherent() is called with a fixed SZ_2M size, but frees happen with IOAT_CHUNK_SIZE. Recently, IOAT_CHUNK_SIZE was reduced to 512M but the allocation did not change. To fix, change to using the IOAT_CHUNK_SIZE define. This was caught with the upcoming patchset for converting Intel platfo
