From 38d8879baeb61b6946052739e7c03fa79b3a57f0 Mon Sep 17 00:00:00 2001 From: Dan Williams Date: Thu, 23 Jun 2011 14:33:48 -0700 Subject: isci: combine request flags Combine three bools into one unsigned long 'flags'. Doesn't increase the request size due to packing. (to do: optimize the structure layout).
