/* proc_handler() / proc_do* API changes
 * 2.6.x  - 2.6.31: 6 args, prototype includes 'struct file *'
 * 2.6.32 - 2.6.y:  5 args, removed unused 'struct file *' from prototype
 *
 * Generic SPL_PROC_HANDLER() macro should be used for correct prototypes.
 * It will define the following function arguments which can and should be
 * used with the spl_proc_* helper macros.
 *
 *   struct ctl_table *table,
 *   int write,
 *   struct file *filp [2.6.31 and earlier kernels],
 *   void __user *buffer,
 *   size_t *lenp,
 *   loff_t *ppos,
