I ran into these while trying to prepare patches to add NBD_CMD_FLAG_FAST_ZERO, which will expose a new NBD_ENOTSUP wire value.

Hi! I am resending the following message about problems with utmp handling. * In the meantime I had some request in private mail from people asking whether I have new information. * The problem is still persistant in 2.9p2. * My own new investigations show, that the problem only appears with protocol 2, not with protocol 1, I therefore only started to note it when protocol 2 became the

From: Yonatan Maman <Ymaman at Nvidia.com> Based on: Provide a new two step DMA mapping API patchset https://lore.kernel.org/kvm/20241114170247.GA5813 at lst.de/T/#t This patch series aims to enable Peer-to-Peer (P2P) DMA access in GPU-centric applications that utilize RDMA and private device pages. This enhancement reduces data transfer overhead by allowing the GPU to directly expose

Hi Andi, This patch series implements the Linux Xen guest as a paravirt_ops backend. The features in implemented this patch series are: * domU only * UP only (most code is SMP-safe, but there's no way to create a new vcpu) * writable pagetables, with late pinning/early unpinning (no shadow pagetable support) * supports both PAE and non-PAE modes * xen hvc console (console=hvc0) *
