I am Subin and I work in RedHat.
I am trying to capture all the details of the glibc patching done in manylinux2010 PEP(https://www.python.org/dev/peps/pep-0571/#compatibility-with-kernels-that-lack-vsyscall)
I was able to dig this email https://mail.python.org/pipermail/wheel-builders/2016-December/000239.html to get some context.
Also this https://github.com/pypa/manylinux/pull/279 .
But I wanted to get the facts right.So I am reaching out to the community on this.
I like to know if there is a system out there in use by community members where vsyscall flag cannot be set to emulate and this patching is absolutely necessary in the Build Image to build a manylinux2010 compliant wheel file ?
If there are more details/links which capture the origin of the patch in the PEP I would be very grateful.
