From: Brian King Date: Mon, 15 Dec 2008 23:09:05 +0000 (-0600) Subject: [SCSI] ibmvfc: Fixup command response translation X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=752b32329b48e0b7481e82a5f891aa5bf01f3782;p=linux-beck.git [SCSI] ibmvfc: Fixup command response translation If a link down event is received, outstanding commands may get returned to the ibmvfc driver with a "transaction cancelled implicit" response. This is currently translated to DID_ABORT, which does not get retried by SCSI core, but rather passes the failure up the stack. This can result in I/O errors at the filesystem level. Fix up this response a well as a few other error responses.
