Linus Torvalds has sent out a note telling people not to install the recent 5.12-rc1 development kernel; this is especially true for anybody running with swap files.
« But I want everybody to be aware of because _if_ it bites you, it bites you hard, and you can end up with a filesystem that is essentially overwritten by random swap data. This is what we in the industry call ‘double ungood’. » Additionally, he is asking maintainers to not start branches from 5.12-rc1 to avoid future situations where people land in the buggy code while bisecting problems.
