/* 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,
