I'm interested on extract original code of Microsoft exFAT File System, and Compile it into my CentOS 8 (I know its the Kernel is very delayed to 5.4 or 5.7 version).

I know the existence of

I'm interested on

https://github.com/torvalds/linux/tree/master/fs/exfat

Would be impossible, but I'm interested in test, and don't want to upgrade my Old Kernel (4.18.0-193) of CentOS 8.2-2004 just patch it.

Is it impossible? then Why?

What consideration I must have?

And What I need to do?

NOTE: The term patch is only add new feature (like a program).

  • Why not just compile the version in the second Github link? There are instructions here: unixtutorial.org/project-compile-exfat-fuse-in-rhel-8 and it won't do anything with the kernel.

  • @NasirRiley according to your link, it is using root@redhat:/dist # git clone https://github.com/relan/exfat.git The mine idea is testing porpouse.

  • So then compile it and test it. If it doesn't do what you want, then make uninstall and delete it. No matter which method you use in your question, you're going to have to compile in order to do anything. There isn't a prebuilt version of it.

What you're looking for is https://download1.rpmfusion.org/free/el/updates/8/x86_64/repoview/fuse-exfat.html

sudo rpm -ivh https://download1.rpmfusion.org/free/el/rpmfusion-free-release-8.noarch.rpm
sudo dnf install fuse-exfat

You don't need to patch anything. Porting the mainline exfat code to your kernel will be a major undertaking I'm pretty sure you're not ready for.

  • Thank you for the confidence vote (lol), you are right! May be I'm not ready, but long time (2004) I was changing C code for Suse Linux, fixing problem with Programs. Now, I'm interested in try, like you maybe I'not get the waited result.

  • @joseluisbz If you're ready and capable, maybe you should send your CV to RedHat. They are interested in backporting mainline kernel features to their own kernels.

  • Thank you. I was reviewing the code of github.com/arter97/exfat-linux vs github.com/torvalds/linux/tree/master/fs/exfat and some files are similar. And the API of 4.18.x kernel has not c functions required in order to translate the fs/exfat from 5.7.x kernel. Maybe I will do work done (Samsung version).
