pnfs-obj: pNFS errors are communicated on iodata->pnfs_error
Some time along the way pNFS IO errors were switched to communicate with a special iodata->pnfs_error member instead of the regular RPC members. But objlayout was not switched over. Fix that! Without this fix any IO error is hanged, because IO is not switched to MDS and pages are never cleared or read. [Applies to 3.2.0. Same bug different patch for 3.1/0 Kernels] CC: Stable Tree <stable@kernel.org> Signed-off-by: Boaz Harrosh <bharrosh@panasas.com> Signed-off-by: Trond Myklebust <Trond.Myklebust@netapp.com>
