    percpu: make pcpu_alloc_chunk() use pcpu_mem_free() instead of kfree() · 5a838c3b
    Jianyu Zhan 提交于
    pcpu_chunk_struct_size = sizeof(struct pcpu_chunk) +
    	BITS_TO_LONGS(pcpu_unit_pages) * sizeof(unsigned long)
    
    It hardly could be ever bigger than PAGE_SIZE even for large-scale machine,
    but for consistency with its couterpart pcpu_mem_zalloc(),
    use pcpu_mem_free() instead.
    
    Commit b4916cb1 ("percpu: make pcpu_free_chunk() use
    pcpu_mem_free() instead of kfree()") addressed this problem, but
    missed this one.
