Subject: [PATCH v5 28/37] KVM: selftests: Export vm_vaddr_unused_gap() to make it possible to request unmapped ranges
Date: Fri, 27 May 2022 17:55:37 +0200 [thread overview]
Message-ID: <20220527155546.1528910-29-vkuznets@redhat.com> (raw)
In-Reply-To: <20220527155546.1528910-1-vkuznets@redhat.com>
Currently, tests can only request a new vaddr range by using
vm_vaddr_alloc()/vm_vaddr_alloc_page()/vm_vaddr_alloc_pages() but
these functions allocate and map physical pages too. Make it possible
to request unmapped range too.
