No, this fix is not correct. I spoke at length with the GFS team and the
porting to 2.6.32 is a lot more complex.

For now we had to put gfs on hold because of the complexity to port it
to 2.6.32 and allow the release of user land tools with many bug fixes.

We are also encouraging people to move away from gfs in favor of gfs2 so
that we can better focus our resources to maintain one file system
instead of two. I donĀ“t think this was ever a secret since gfs2 is part
of kernel upstream and gfs1 is not and never will :)

So basically, the code is there and builds (with the restriction to the
kernel version), it will receive bug fixes, but we want to make it a
user conscious choice that they are building something that will
disappear in the future (hence the requirement to explicitly enable gfs
build).

GFS2 has become a lot more stable with recent kernel releases but please
file BZs for any problem you might find.

I did CC the GFS team in case you might have more specific questions.

Cheers
Fabio
