那是Linux内核的补丁。如果您还没有 Linux 内核源代码,则需要从一个克隆开始:
$ git clone git://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git
然后你需要下载补丁。不要试图从您的网络浏览器复制和粘贴它。您可以从https://patchwork.kernel.org/下载内核补丁;您引用的补丁似乎是https://patchwork.kernel.org/patch/8182901。从这里下载mbox
补丁版本,它将保存到一个名为. 然后,您可以通过在 linux 源目录中运行命令来应用此补丁:
v5-fuse-Add-support-for-passthrough-read-write.patch
git am
$ cd linux
$ git am /path/to/v5-fuse-Add-support-for-passthrough-read-write.patch
但是看看这个补丁,它是从 2016 年 2 月开始的,所以它可能不会完全适用于当前版本的内核。“可能”,我的意思是“它不适用”;上面的命令导致:
Applying: fuse: Add support for passthrough read/write
error: patch failed: fs/fuse/Makefile:5
error: fs/fuse/Makefile: patch does not apply
error: patch failed: fs/fuse/file.c:252
error: fs/fuse/file.c: patch does not apply
error: patch failed: fs/fuse/fuse_i.h:531

The copy of the patch that failed is found in: .git/rebase-apply/patch
When you have resolved this problem, run "git am --continue".
If you prefer to skip this patch, run "git am --skip" instead.
To restore the original branch and stop patching, run "git am --abort".
所以我们需要做的是将内核源代码回滚到 2016 年的样子。首先,我们需要中止正在进行的git am
操作:
$ git am --abort
然后将源回滚到 2016 年 2 月 1 日或前后:
$ git checkout $(git rev-list -1 --before=2016-02-02 --first-parent master)
现在补丁干净地应用了:
$ git am /path/to/v5-fuse-Add-support-for-passthrough-read-write.patch
Applying: fuse: Add support for passthrough read/write
应用补丁后,您将需要编译和安装新的内核和模块,这超出了此答案的范围,但有据可查。
要问自己的问题是,鉴于这个补丁已经有一年多了,并且从未被内核接受,你确定你需要它吗?从那以后是否有其他可能提供类似改进的变化?
