I've created RPMs using the source (1.6.21.1) with this patch and have
installed it on several systems running the latest RHEL 7.4 kernel. I
haven't noticed any issues from the fixes (can't say my testing has been
exhaustive though), but these also aren't very busy systems and I also
haven't ever seen the getcwd issues on these systems either.

It has been decided that we will wait for a new official OpenAFS release
with this fix before putting/testing it on any production, busier systems
where we've seen the getcwd issue occur, instead of using a patched source
for these systems.

So, as soon as a new 1.6.x release comes out with this fix (either the
1.6.x backport or the larger changes), we'll be sure to test it more and
confirm that we don't encounter the same getcwd issue anymore as well.

Thanks!
