| |
The k[v]free_rcu() macro's single-argument form is deprecated. Therefore switch to the new k[v]free_rcu_mightsleep() variant. The goal is to avoid accidental use of the single-argument forms, which can introduce functionality bugs in atomic contexts and latency bugs in non-atomic contexts.
The callers are holding a mutex so the context allows blocking. Hence using the API with a single argument will be fine, but use its new name.
There is no functionality change with this patch.
