 The Magic SysRQ system works by registering key operations against a key op
 lookup table, which is defined in 'drivers/char/sysrq.c'. This key table has
 a number of operations registered into it at compile time, but is mutable,
-and 2 functions are exported for interface to it:
-	register_sysrq_key and unregister_sysrq_key.
-Of course, never ever leave an invalid pointer in the table. I.e., when
-your module that called register_sysrq_key() exits, it must call
-unregister_sysrq_key() to clean up the sysrq key table entry that it used.
-Null pointers in the table are always safe. :)
+and 4 functions are exported for interface to it: __sysrq_lock_table,
+__sysrq_unlock_table, __sysrq_get_key_op, and __sysrq_put_key_op. The
+functions __sysrq_swap_key_ops and __sysrq_swap_key_ops_nolock are defined
+in the header itself, and the REGISTER and UNREGISTER macros are built from
+these. More complex (and dangerous!) manipulations of the table are possible
+using these functions, but you must be careful to always lock the table before
+you read or write from it, and to unlock it again when you are done. (And of
+course, to never ever leave an invalid pointer in the table). Null pointers in
+the table are always safe :)
 
 If for some reason you feel the need to call the handle_sysrq function from
 within a function called by handle_sysrq, you must be aware that you are in
