  * @bug 8315923
  * @requires vm.gc.Parallel & os.family == "linux" & os.maxMemory > 30G
  * @summary Check if parallel pretouch performs normally with and without THP.
+ * @comment The test is not ParallelGC-specific, but a multi-threaded GC is    \
+ *          required. So ParallelGC is used here.
