Well, I can't figure out from dmesg - it's all I have from that run - which fs it was. So lemme give you all ext4 ones:
$ mount | grep ext4 /dev/nvme0n1p2 on / type ext4 (rw,relatime,errors=remount-ro) /dev/sdc1 on /home type ext4 (rw,noatime) /dev/sda1 on /mnt/oldhome type ext4 (rw,noatime) /dev/sdb1 on /mnt/smr type ext4 (rw,noatime) /dev/nvme1n1p1 on /mnt/kernel type ext4 (rw,nosuid,nodev,noatime,user)

Good question. I'm not sure. Kernel build is likely as I do those on that workstation constantly.
Unfortunately, I don't have an exact reproducer. And I can't debug stuff on that box since it is my workstation and I've reverted it to 5.14.
What I can do is, I can slap 5.15-rc4 or whichever version you'd want me to, on a test box and try running kernel builds or some other load to see whether it would fire. I have a similar box to my workstation.
Or if you have a better idea...
