Subject: Re: [PATCH v4 2/6] KVM: Add file back-pointer to struct kvm
Date: Mon, 28 Sep 2026 13:18:54 +0000 [thread overview]
Message-ID: <20260928131855.268541F000FF@smtp.kernel.org> (raw)
In-Reply-To: <20260928-vfio-v4-2-e32e226d5932@linux.ibm.com>
> Add kvm->file as a no-reference back-pointer to the VM file in struct
> kvm. The pointer is set at VM creation time and cleared under
> WRITE_ONCE() in kvm_vm_release() before the file is freed.
> Callers storing the file must take their own reference.
