Surely this is considered a serious installer bug? Users who choose an option
called "raid1" with btrfs would, and should, expect to have data redundancy.
Even if this bug has existed for a long time, it doesn't make it any less
dangerous.

I forgot to mention that bfq appears to be the only IO scheduler that supports
cgroups-v2 IO controllers [1]. Perhaps I am wrong, but I wasn't able to find
documentation indicating that mq-deadline is cgroup-aware, at the very least

Yep, I just ran "dnf info kernel" and then right after that "dnf changelog

Does zswap actually keep the data compressed when the DRAM-based swap is full,
