绿色部分 --- find its way to xxx, 这里的way和路径无关。直接翻译成“内存中的数据必须写入磁盘设备” 比较合适

LWN 384093: issues - 3rd paragraph

红线部分翻译的不是很准确。我个人的翻译意见是“在理想情况（调用链很短）下，能用的内核栈空间就很少。而direct relaim可能在任意的地方被调用，调用链可能非常长，所以留给direct reclaim的内核栈就更少了”

cannot count on finding the best of conditions意思是不能指望最好的情况，说明direct reclaim于东的情况会更差

• LKML: RISC-V Hypervisors

It’s a great pleasure to inform everyone that we have RISC-V hypervisor extension available for QEMU and along with it we also have Xvisor (a baremetal type-1 hypervisor) working on QEMU with RISC-V hypervisor extension. Currently, we are able to boot two Linux RV64 Guests on Xvisor RV64.

关键词：RISC-V，Xvisor, Qemu, Hypervisor。

RISC-V 作为完全开源的处理器架构，当前的发展如日中天，它的 Qemu 开发支持也在火热进行中。有了基础的 Qemu 模拟和上面的 Hypervisor 支持以后，RISC-V 的后续软硬件开发效率将大大提高，国内的厂商们速度跟进哈。
