Subject: Re: [PATCH v3 2/5] KVM: Add file back-pointer to struct kvm
Date: Thu, 24 Sep 2026 09:07:06 +0000 [thread overview]
Message-ID: <20260924090706.ACEA81F000FF@smtp.kernel.org> (raw)
In-Reply-To: <20260924-vfio-v3-2-4a294307797b@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.
