Has this regression been fixed in 5.4.38? I'm not sure.

There are ext4 fixes in all the updates.


I would guess so..?


Edit: Actually looking at the changelog(s) I'm not quite as sure...

I'm going to come right out and say this. LTS kernels... damned if you do, damned if you don't. Backporting breaks things, it's like trying to sew new arms on an octopus.

Don't bother with 5.4.26 folks, just wait for the next one. Trust me
That's atrocious, upgrading in good faith expecting bug fixes and having those bug fixes break things in the kernel.

The regression seems to be introduced in v4.7 with:

1f60fbe72749 ("ext4: allow readdir()'s of large empty directories to be interrupted")
... and why the Hell should an empty directory stay "large"? Something should be done about THAT. There should be some mechanism to shrink them when large size is no longer needed to store directory entries.

I always found that so stupid (and I don't think this is Linux/ext* fs specific). Some years ago, on a RHEL+Plesk server I was looking after (primary role was a busy vbulletin/vbportal site) php session files were piling up to the point that it used up all the inodes on the filesystem. I dutifully stopped the web server, renamed the directory, put down a new one and then proceeded to delete the old one. I couldn't do it, the directory file was so large (~990 Mb) the command was hanging. So I proceeded to delete the files by wildcards (from above it, without entering), in increments to avoid hangs/OOM. Got them deleted, and got the inodes back, but the directory did not shrink and I couldn't delete it. It remained there, for all time, for the lifetime of the server. Forced e2fsck wasn't fixing it, as far as it knew there was nothing wrong with it. No big deal, I removed permissions so nothing could read or traverse it, but it pissed me off.

I know that, but Pat was reasonably quick to compile 5.4.39 and provide packages for -current, so kudos to him.
