Rename k[v]free_rcu() single argument to k[v]free_rcu_mightsleep()

[PATCH 03/13] misc: vmw_vmci: Rename kvfree_rcu() to kvfree_rcu_mightsleep()

Posted by Uladzislau Rezki (Sony) 2 years, 7 months ago

The kvfree_rcu()'s single argument name is deprecated therefore
rename it to kvfree_rcu_mightsleep() variant. The goal is explicitly
underline that it is for sleepable contexts.
