I would find it nicer if you would have extended my simple wording suggestion.

1. Mention conditions:
   The callback function “rcu_free_wq” could be called after memory was released
   for “rescuer” already.

2. Specify the desired action:
   Thus delete a misplaced call of the function “kfree”.

3. Please keep the patch versioning consistent.
