      That's some pretty strong language there about the FSGSBASE code being an "Engineering Trainwreck", but it's probably warranted if what the kernel devs who have had a closer look at the code is anything to go on. Actually, the description is probably fairly tame considering I'd have called it a "Sh*tshow" or a "Trashfire" had something like that landed on my desk.
