Subject[PATCH] rcu: remove unused __kfree_rcu inline functions
Date
Patch "rcu: Make __kfree_rcu() less dependent on compiler choice"
from Jan Engelhardt intended to replace the inline functions
__kfree_rcu and __is_kfree_rcu_offset with macros.

Unfortunately, the patch only added the new macros but did not
remove the old inline functions. This patch removes them finally.

With the unused functions still being around, module builds with
-O0 still fail.
