This is a preparation for debugfs restricted mode. We don't need debugfs to trace, the removed check stop tracefs to work if debugfs is not initialised. We instead tries to automount within debugfs and relay on it's handling. The code path is to create a backward compatibility from when tracefs was part of debugfs, it is now standalone and does not need debugfs. When debugfs is in restricted it is compiled in but not active and return EPERM to clients and tracefs wont work if it assumes it is active it is compiled in kernel. Reported-by:
