More precisely:
- The last working commit is b6dff3ec... "CRED: Separate task
security context from task_struct".
- The first commit exhibiting the permissions problem is
a6f76f2... "CRED: Make execve() take advantage of
copy-on-write credentials".
- The 9 commits in between (from f1752eec to d84f4f9) result in
a soft lookup on boot.
