checkpatch: Error out if deprecated RCU API used
Single-argument kvfree_rcu() usage is being deprecated [1] [2]. However,
till all users are converted, we would like to introduce checkpatch
errors for new patches submitted.
This patch adds support for the same. Tested with a trial patch.
For now, we are only considering usages that don't have compound
nesting, for example ignore: kvfree_rcu( (rcu_head_obj), rcu_head_name).
This is sufficient as such usages are unlikely.
Once all users are converted and we remove the old API, we can also revert this
checkpatch patch then.
