Thanks for this fix. Linus has picked it up (inclusive the typos to the x86_fsgsbase_read_task() function name ;-), it's now upstream under:
8ab49526b53d: ("x86/fsgsbase/64: Fix NULL deref in 86_fsgsbase_read_task")
By the fixes tag it looks like this should probably be backported all the way back to ~v4.20 or so?
Thanks,
Ingo
