Subject: [PATCH 3.18 21/85] scsi: vmw-pvscsi: return DID_BUS_BUSY for adapter-initated aborts

3.18-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Jim Gill <jgill@...are.com>

[ Upstream commit f4b024271ae3e9786e5d6f1c05b01b57a74e1d6d ]

The vmw_pvscsi driver returns DID_ABORT for commands aborted internally
by the adapter, leading to the filesystem going read-only. Change the
result to DID_BUS_BUSY, causing the kernel to retry the command.
