'...the problem with this 5.12 release candidate broke swapfile handling in a very unpleasant way. Specifically, the updated code would lose the proper offset pointing to the beginning of the swapfile. Again, in Torvalds' own words, "swapping still happened, but it happened to the wrong part of the filesystem, with the obvious catastrophic end results."'
Note that only swap files were affected, not swap partitions. Seems Ubuntu likes to use swap files, while others stick to swap partitions. The article points out that swap files have lower performance as well as complexity issues.
