+    elf: Fix comments and logic in _dl_add_to_slotinfo
+    
+    Since
+    
+      commit a509eb117fac1d764b15eba64993f4bdb63d7f3c
+      Avoid late dlopen failure due to scope, TLS slotinfo updates [BZ #25112]
+    
+    the generation counter update is not needed in the failure path.
+    That commit ensures allocation in _dl_add_to_slotinfo happens before
+    the demarcation point in dlopen (it is called twice, first time is for
+    allocation only where dlopen can still be reverted on failure, then
+    second time actual dtv updates are done which then cannot fail).
