--- Comment #115 from Duncan (1i5t5.duncan@cox.net) --- So 5.8.0 has been out for a few hours with the patch-fix, and I see Greg K-H has it applied to the 5.7 stable tree as well as 5.4 LTS (the bug was in 5.4 but latent, not exposed until developments in 5.7), so they should be covered in their next releases.
