Hey Steve,

I've started seeing memory corruption issues in LKFT, such as the one
here: https://qa-reports.linaro.org/lkft/sashal-linus-next/build/v6.13-rc7-790-gabac258eb0d1/testrun/26834686/suite/log-parser-test/test/bug-bug-kernel-null-pointer-dereference-address/log

I ran a bisection, which led me to the below commit:

I've also confirmed that reverting this commit on top of linus-next fixes
the issue.
