+Subject: [PATCH 248/347] drivers/zram: fix zcomp_stream_get()
+ smp_processor_id() use in preemptible code
+Origin: https://www.kernel.org/pub/linux/kernel/projects/rt/4.19/older/patches-4.19.246-rt110.tar.xz
+
+Use get_local_ptr() instead this_cpu_ptr() to avoid a warning regarding
+smp_processor_id() in preemptible code.
+raw_cpu_ptr() would be fine, too because the per-CPU data structure is
+protected with a spin lock so it does not matter much if we take the
+other one.
