Why was the reallocarray function not added to glibc?

[Dennis Wölfing]

The reallocarray function is a useful function that originates from 
OpenBSD and
that checks for overflow when (re)allocating memory. I saw in the mail 
archives
that a patch that implements reallocarray was already contributed in May 
2014.

Here is the link: https://sourceware.org/ml/libc-alpha/2014-05/msg00481.html

However this patch was never applied even though I could not find any real
objections in the mail archives.

Is there any reason to not add reallocarray to glibc? If not, should the 
patch
linked above be applied?
