The Debian bug is really light on details, so here is the git commit
that fixes this:
http://nbd.git.sourceforge.net/git/gitweb.cgi?p=nbd/nbd;a=commitdiff;h=ebbbe0b3ce5393fa42a259f5e03d549508586aaa
But I don't see any evidence that this _only_ affects 2.9.21. Are we
sure that it doesn't affect earlier versions? The reporter doesn't
indicate one way or the other.
CC'ing Wouter for clarification.
