Subject: [PATCH] netfilter: nf_tables: Add __percpu annotation to *stats pointer in nf_tables_updchain()
Compiling nf_tables_api.c results in several sparse warnings:
nf_tables_api.c:2740:23: warning: incorrect type in assignment (different address spaces)
nf_tables_api.c:2752:38: warning: incorrect type in assignment (different address spaces)
nf_tables_api.c:2798:21: warning: incorrect type in argument 1 (different address spaces)
Add __percpu annotation to *stats pointer to fix these warnings.
Found by GCC's named address space checks.
There were no changes in the resulting object files.
