Is there a more topic-focused one than videography or fieldrecording?

Two things I'd love to know the under-the-hood reasons for, and I assume both might have to do with its copy-on-write nature, which I admit I still don't fully understand.

1. Unlike I know from NTFS (and maybe also EXT?), on BTRFS I can move a folder containing tens of thousands of files to a new location on the media and it happens instantly, not even touching any of those file names, it seems. This actually seems natural to me and NTFS making a big fuss about it as clumsy.

2. But then when I simply delete a large file (like 150 GB), for a couple seconds nothing happens in regards to free space, and then after maybe 20 seconds it starts to slowly free up that file's space, as if it was running a TRIM command on a harddrive. This is inconvenient because I wanted to copy a newer version of that file and it told me there's not enough space and so I had to wait before I could copy the new version.

Thanks for insights!

For a long time I used Mainline Kernels to install newer kernels than the default 6.8. Now I realized that it seems there are newer options offered natively; I saw them in Synaptic package manager. But when trying to install for example 6.17 (expecting better updates provided like for the current Copy Fail exploit), it says it is listed in the database but there is no source (or such). Now it went to a next step and says there are unresolved dependencies and that I should add all required repos.

How do I get this to work properly?

Is it related to currently using a 6.17 kernel installed via Mainline Kernels?

linux-lowlatency-6.17:
Depends: linux-image-generic-6.17 but it is not going to be installed
Depends: linux-headers-generic-6.17 (=6.17.0-23.23~24.04.1) but it is not installable
Depends: lowlatency-kernel but it is not going to be installed
Recommends: linux-tools-6.17.0-23-generic but it is not installable
