                        KVM_DIRTY_LOG_INITIALLY_SET is enabled or disabled. If
                        disabled, all huge pages in a memslot will be eagerly
                        split when dirty logging is enabled on that memslot. If
-                       enabled, huge pages will not be eagerly split.
+                       enabled, eager page splitting will be performed during
+                       the KVM_CLEAR_DIRTY ioctl, and only for the pages being
+                       cleared.
 
                        Eager page splitting currently only supports splitting
                        huge pages mapped by the TDP MMU.
