--- Additional comment from Kevin Wolf on 2016-11-07 11:00:36 CET ---

Fixed with upstream commits 94d6a7a7 and aa2623d8. The first one does the actual
fix (by rewriting the code), but it doesn't build without the second commit.

Resetting the assignee as I can't change Fedora packages.

Comment 3 Kevin Wolf 2017-04-25 09:14:36 UTC
Ping Li pointed out that we don't even compile in the NFS driver in RHEL, so this
bug report is obviously invalid here. It is valid only for Fedora. Sorry for the

(But I did check that it is indeed fixed in our source tree, so even if we
decide to enable the driver one day, we're okay.)
