commit: 225c56960fcafeccc2b6304f96cd3f0dbf42a16a From: Benjamin Herrenschmidt <[email protected]> Date: Mon, 30 Jul 2012 11:33:05 +1000 Subject: [SCSI] ibmvscsi: Fix host config length field overflow
The length field in the host config packet is only 16-bit long, so passing it 0x10000 (64K which is our standard PAGE_SIZE) doesn't work and result in an empty config from the server.
