No, I didn't actually test it with GFS2. I just based my change on the fact
that the GFS2 bug 678585 has been closed as fixed in 2011, and that I using
fcntl is typically recommended. Also it looks like NIO uses fcntl, so I would
guess that NIO also didn't work with that GFS2 bug. I can try setting up a GFS2
file-system, but I haven't done it before. This would probably take at least a
few days, maybe next week.
