Please don't revert my patch.  Please try this patch:

https://sourceware.org/git/?p=glibc.git;a=commit;h=4b7fc470a6740808b41502d7431f91805e272d26

instead.  I will clean it up and submit it tomorrow.

This is unacceptable. It adds a new symbol version and we froze the
ABI at the start of the month. You cannot work these fixes into 2.27
with a new symbol version, it must wait for 2.28.


Note that the actually posted patch is completely different.

Thanks,
Florian
