From f885fb73f64154690c2158e813de56363389ffec Mon Sep 17 00:00:00 2001 From: "K. Y. Srinivasan" Date: Sat, 12 Jul 2014 09:48:31 -0700 Subject: [PATCH] drivers: scsi: storvsc: Set srb_flags in all cases Correctly set SRB flags for all valid I/O directions. Some IHV drivers on the Windows host require this. The host validates the command and SRB flags prior to passing the command down to native driver stack. Signed-off-by: K. Y.
