6.6-stable review patch. If anyone has any objections, please let me know. ------------------ From: Shantanu Goel <sgoel01@xxxxxxxxx> [ Upstream commit 9d32685a251a754f1823d287df233716aa23bcb9 ] Set the host status byte when a data completion error is encountered otherwise the upper layer may end up using the invalid zero'ed data. The following output was observed from scsi/sd.c prior to this fix.
