[Qemu-devel] [PATCH v3 0/2] xen: fix qdisk BLKIF_OP_DISCARD for 32/64 word size mix

2016-06-20 Thread Juergen Gross
In case the word size of the domU and qemu running the qdisk backend differ BLKIF_OP_DISCARD will not work reliably, as the request structure in the ring have different layouts for different word size. Correct this by copying the request structure in case of different word size element by element
