A warning about 5.12-rc1

Linus Torvalds has sent out a note telling people not to install the recent5.12-rc1 development kernel; this is especially true for anybody runningwith 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 thatis essentially overwritten by random swap data. This is what we in theindustry call 'double ungood'." Additionally, he is askingmaintainers to not start branches from 5.12-rc1 to avoid future situations wherepeople land in the buggy code while bisecting problems.
