Subject: [PATCH v4 05/13] KVM: selftests: Add missing close and munmap in __vm_mem_region_delete
Date: Fri, 24 Jun 2022 14:32:49 -0700	[thread overview]
Message-ID: <20220624213257.1504783-6-ricarkol@google.com> (raw)
In-Reply-To: <20220624213257.1504783-1-ricarkol@google.com>

Deleting a memslot (when freeing a VM) is not closing the backing fd,
nor it's unmapping the alias mapping. Fix by adding the missing close
and munmap.
