Head is 6002817348a1c610dc1b1c01ff81654cdec12be4 it renames a single argument of k[v]free_rcu() to its new k[v]free_rcu_mightsleep() name. 1. The problem is that, recently we have run into a precedent when a user intended to give a second argument to kfree_rcu() API but forgot to do it in a code so a call became as a single argument of kfree_rcu() API. 2. Such mistyping can lead to hidden bags where sleeping is forbidden. 3. _mightsleep() prefix gives much more information for which contexts it can be used for.
