* Adhemerval Zanella via Libc-alpha:

> And use it on readdir_r implementation.

I think __readdir_unlocked will not really be async-signal-safe if we
have to call malloc during readdir, to allocate the long-to-off64_t
translation table for the real fix for bug 23960 (when the kernel does
not provide 32-bit off64_t values).

That's why I think this change does not go in the right direction, sorry.
