From 22956a3755749b9cf6375ad024d58c1d277100bf Mon Sep 17 00:00:00 2001 From: Alexey Kardashevskiy Date: Wed, 5 Mar 2014 16:15:16 +1100 Subject: [PATCH] spapr-vscsi: fix CRQ status Normally VIOSRP_OK (0) means success and non-zero value means error except VIOSRP_OK2 (0x99) which is another success code by weird accident. This uses 0 as success code always as some guests do not cope with the 0x99 value well. The existing linux driver checks for both VIOSRP_OK and VIOSRP_OK2 since 2.6.32. This returns non-zero code (VIOSRP_ADAPTER_FAIL == 0x10) on errors which can only happen if DMA write failed.
