 Unfortunately the commit listed in the subject line above failed
 to ensure that the task's audit_context was properly initialized/set
 before enabling the "accompanying records".  Depending on the
 sitation, the resulting audit_context could have invalid values in
 some of it's fields which could cause a kernel panic/oops when the
 task/syscall exists and the audit records are generated.
 We will revisit the original patch, with the necessary fixes, in a
 future kernel but right now we just want to fix the kernel panic
 with the least amount of added risk.

William pointed out a misspelling in the patch description above,
which I just fixed.  Unfortunately I had already pushed the patch to
audit/stable-5.8 so I did a force-push to correct the spelling;
normally I wouldn't do something like that for such a trivial matter,
but since it is unlikely anyone is based of the audit/stable-5.8
branch this seemed like an okay time to do that.
I'll be sending a PR to Linus shortly.
