Comment 49 for bug 1863162

Hello, it seems this bugfix has reached Ubuntu 22.04, which is nice. However some of my users use earlier Ubuntu versions (18.04 and 20.04) where it is not available. How can I apply the fix on those versions? I tried checking out the glibc version available in Ubuntu 18.04 (2.27) and cherry-picking the fixes. But I get a conflict I don't know how to solve because the base files are very different.
