mm/z3fold: add __percpu annotation to *unbuddied pointer in struct z3fold_pool
Compiling z3fold.c results in several sparse warnings: z3fold.c:797:21: warning: incorrect type in initializer (different address spaces) z3fold.c:797:21: expected void const [noderef] __percpu *__vpp_verify z3fold.c:797:21: got struct list_head * z3fold.c:852:37: warning: incorrect type in initializer (different address spaces) z3fold.c:852:37: expected void const [noderef] __percpu *__vpp_verify z3fold.c:852:37: got struct list_head * z3fold.c:924:25: warning: incorrect type in assignment (different address spaces) z3fold.c:924:25: expected struct list_head *unbuddied z3fold.c:924:25: got void [noderef] __percpu *_res z3fold.c:930:33: warning: incorrect type in initializer (different address spaces) z3fold.c:930:33: expected void const [noderef] __percpu *__vpp_verify z3fold.c:930:33: got struct list_head * z3fold.c:949:25: warning: incorrect type in argument 1 (different address spaces) z3fold.c:949:25: expected void [noderef] __percpu *__pdata z3fold.c:949:25: got struct list_head *unbuddied z3fold.c:979:25: warning: incorrect type in argument 1 (different address spaces) z3fold.c:979:25: expected void [noderef] __percpu *__pdata z3fold.c:979:25: got struct list_head *unbuddied Add __percpu annotation to *unbuddied pointer to fix these warnings.
