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).
