Subject: [PATCH 07/10] kvm: struct kvm_memory_slot.user_alloc -> bool
Date: Thu, 06 Dec 2012 15:21:09 -0700	[thread overview]
Message-ID: <20121206222109.24968.26023.stgit@bling.home> (raw)
In-Reply-To: <20121206214722.24968.6043.stgit@bling.home>

There's no need for this to be an int, it holds a boolean.
Move to the end of the struct for alignment.
