This may not be true, e.g. when loading multiple kernel\nmodules which are linked to the same object file. As a result, loading\nsuch kernel modules will result in incorrect gcov results while unloading\nwill cause a null-pointer dereference.\n\nThis patch fixes these problems by changing the gcov-kernel infrastructure\nso that multiple profiling data sets can be associated with one debugfs\nentry.
