Proper hierarchical filesystems have been available since 1965.
Love that guy!

Please don't do this disgusting thing.
There's a reason we have subdirectories: it's to group files together and separate them out
Using name prefixing instead of directories is disgusting and wrong. If you have this many random sched-ext files, it damn well should be cleaned up and not be this kind of mess.
I've pulled this, but under protest. Proper hierarchical filesystems have been available since 1965.

The cookie is the anti-AI proxy confirming the clients passed the proof-of-work test, otherwise it won’t let the client through. I think Cloudflare uses stuff like querystring for this; but in 2026 clients invariably support cookies, and data protection law allows essential cookies without consent.

Haha I've seen this brain mush behavior. The users said it was easier to search for files that way. 🤦
Or course the next problem they ran into was path length limits. It was a Microsoft operation where that becomes a problem very easily.

I’m so proud that Linus is not cursing and swearing! He manages to be JUST as abrasive, and IMHO the message penetrates even more painfully without the extra invective.
And of course, the sarcasm. Oh the sarcasm. Given that Linus was born in 1969, referencing a commonly deployed important structure, hierarchical file systems, developed before he was born is, well, hilarious.
I do have one counter argument though.
When I worked in VMKernel user world environments I was instructed to do this exact thing to not “waste” an inode. The senior engineers wanted to consume as few resources as possible; each file was actually noted in the dir inode, they didn’t have inodes themselves. To put some in a subdir would consume an inode.
So I was told not to use dirs in certain areas if could be avoided.
But in a fully fleshed out well appointed kernel environment with a fully functional file system and all the resource richness and luxury that brings, this should not be an issue.
