Hi Peter,

Thank you for the confirmation. Glad to hear the patch has been apporved!

This is my first contribution to glibc, and I currently do not have 
commit access. It would be greatly appreciated if someone could help 
push this upstream. Please let me known if there is anything I need to 
do on my side to assist with the process.

Best regards,
