It does, and Maxime's patch has already been merged into the apparmor
tree, as well as mainline:
https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=4de32fd05ce9e63b492899215ea929e7d306cdab
The patch I'm proposing is still needed to fix the earlier race at the
beginning of update_sk_ctx.
