I had a swapfile configured like in https://wiki.manjaro.org/index.php?title=Swap#Creating_and_Enabling_a_Static_Swapfile. After the latest update, I noticed in htop and swapon that it's not active. When doing
sudo swapon /swapfile
swapon: /swapfile: swapon failed: Invalid argument
I fixed it by recreating the swapfile using
sudo dd if=/dev/zero of=/swapfile count=4096 bs=1MiB instead of fallocate and it works.
Should the wiki be updated?
