+Subject: [PATCH 062/347] locallock: provide {get,put}_locked_ptr() variants
+Origin: https://www.kernel.org/pub/linux/kernel/projects/rt/4.19/older/patches-4.19.246-rt110.tar.xz
+
+Provide a set of locallocked accessors for pointers to per-CPU data;
+this is useful for dynamically-allocated per-CPU regions, for example.
+
+These are symmetric with the {get,put}_cpu_ptr() per-CPU accessor
+variants.
