The updated kernel was released, and it fixes the performance regression. Thank you!

[Test Plan] * autopkgtest pass * kernel regression zfs testsuite pass * zsys integration test pass [Where problems could occur] * The stable branches maintain api/abi. Certain bugfixes do change userspace visible behavior of either succeeeding (when previously operations failed), or return errors when previously succeeding in error. For example there are changes when unlinking files in full volumes; changes to fallocate behaviour, etc. Overall they are minor corner cases, and bugfixes to correct the bahaviour to what is universally expected and how things behave on other filesystems (i.e. ext4).
