From 32d92586629a8b3637a3c9361709818e25f327ad Mon Sep 17 00:00:00 2001 From: "Steven Rostedt (VMware)" Date: Wed, 27 Mar 2019 20:07:31 -0400 Subject: syscalls: Remove start and number from syscall_set_arguments() args After removing the start and count arguments of syscall_get_arguments() it seems reasonable to remove them from syscall_set_arguments(). Note, as of today, there are no users of syscall_set_arguments(). But we are told that there will be soon. But for now, at least make it consistent with syscall_get_arguments().
