Comment 36 for bug 1796292

I was looking into kernel commits and I came across this: https://github.com/torvalds/linux/commit/fadd94e05c02afec7b70b0b14915624f1782f578

So, as far as I understood, it actually deals with the issue of manual device detach during a writeback clean-up and causing deadlock. The timeline makes sense when we look for Bionic GA kernel, as well. Bionic GA should not include this fix, but HWE should.

Could we run the tests again, but focusing on Bionic hwe? Afair hwe runs 4.18, which should include this commit.
