percpu-refcount: cosmetic updates
* s/percpu_ref_release/percpu_ref_func_t/ as it's customary to have _t postfix for types and the type is gonna be used for a different type of callback too. * Add @ARG to function comments. * Drop unnecessary and unaligned indentation from percpu_ref_init() function comment. Signed-off-by: Tejun Heo <tj@kernel.org> Acked-by: Kent Overstreet <koverstreet@google.com>
