+@item dwatch[/T] @var{addr} [ @var{task} ]
+Clears a watchpoint previously set for a region.
+Without @code{T} option, @var{addr} is assumed to be a kernel address.
+If you want to clear a watch point in user space, specify @code{T} and
+@var{task} parameter where the address belongs to. If the @var{task}
+parameter is omitted, a task of the default target thread or a current
+task is assumed. If you specify a wrong space address, the request is
+rejected with an error message.
