I'm not sure that symlink example is all right. Symlink is just a special kind of file that just contains a path. It does not points directly to the inode, that would be a hardlink, which you can't create between different file systems. With symlink, I believe, it should go back to the begining, just with a new filepath to find.

Thank you for the video, it was very nice and informative!

Fun fact: Unix was the first operating system to treat files as streams of bytes and abstract physical and logical records

Great work again!!, excited for linux 6.12 video

[babudelhi]

I'm curious what software do you use for video production for explanation animations

[whtiequillBj]

Wonderful video. Can you make, or suggest, a video on Windows IFS and how it differs from VFS.
There are some ext4 and btrfs IFS drivers

Your example at 6:15 have the chain of inode broken :)

This is an excellent video, and it also shows how impressive the Linux kernel is as a free and open-source software. However, a question that stuck with me is how much memory that inode list uses and how the kernel determines the size limit for caches in general.

[PerriPaprikash]

as others have noted there a serveral glaring explanation errors. You should consider fixing them and reuploading the video.

[jps]

what did you use to make those diagrams?

[DariaTimurovich]

1:58 that's not callback functions, that's wrapper functions

[Liyiqi-ei]

Too many things are abstracted by the operating system!
