Subject: [PATCH v2 03/11] KVM: selftests: Add vm_alloc_page_table_in_memslot library function
Date: Wed, 23 Mar 2022 15:53:57 -0700	[thread overview]
Message-ID: <20220323225405.267155-4-ricarkol@google.com> (raw)
In-Reply-To: <20220323225405.267155-1-ricarkol@google.com>

Add a library function to allocate a page-table physical page in a
particular memslot.  The default behavior is to create new page-table
pages in memslot 0.
