Hyper-V's Balloon Driver Causes systemd-journald Goes Crazy
Hello community!
I'm currently using Arch Linux via Hyper-V for work because I like its efficiency and speed. However, there is one thing that bugged the virtual machine:

As you can see, systemd-journald takes a lot of CPU usage for nothing. This usually happens after I compiled a C program or other heavy jobs. After that occurred, dynamic memory seems stopped working. So I check dmesg (with tail pipe) and it shows:

Pretty sure something wrong on kernel module for hv_balloon. I'm going to send issue to upstream regarding this trouble. Anyway, is there any workaround to prevent this for now? Thanks!
Note: In case of missing image, here's the permanent link.

Looks weird, can't really say much beyond that, what does the journal itself contain when you check it? Might be able to play around with some of the journald config options: https://man.archlinux.org/man/journald.conf.5

Honestly, the word "weird" is rather relative but I'm okay with your opinion. Anyway, I can't see any further from kernel logs due to hv_balloon throwing a lot of logs. Here's the systemd logs.
There is no /etc/systemd/journald.conf.d directory but I have /etc/systemd/journald.conf. Any idea which line should I uncomment?
