Subject: [PATCH v8 06/14] KVM: selftests: Stash backing_src_type in struct userspace_mem_region
Date: Thu, 22 Sep 2022 03:18:49 +0000	[thread overview]
Message-ID: <20220922031857.2588688-7-ricarkol@google.com> (raw)
In-Reply-To: <20220922031857.2588688-1-ricarkol@google.com>

Add the backing_src_type into struct userspace_mem_region. This struct
already stores a lot of info about memory regions, except the backing
source type.  This info will be used by a future commit in order to
determine the method for punching a hole.
