The impish kernel returns "not supported" when fallocate is used in the way mysql does it. That makes mysql aware of the problem, and switch strategies, and it works.

The jammy kernel is saying all is fine with the call and its results, but it isn't. Mysql, or any userspace, shouldn't be second guessing the kernel.

We will test it and put in the release notes as a workaround if it works.
