[Bug 1645232] Re: e2fsprogs - could not preserve ACL permissions : The getxattr() returns with (EINVAL)

[Alfonso Sanchez-Beato]

I am getting this in bionic, with e2fsprogs 1.44.1-1. In fact, I have
tried with e2fsprogs upstream and happens as well. I have simply
followed the instructions in the bug description to reproduce.

So, somewhat, although part of the patch was included upstream, it did
not fix completely the issue.
