Parent article: Kernel release status

I know a lot of people prefer OCFS2 to GFS, because of the simpler, more "Linux-like" design. Is this still the case with GFS2? I would like to request an LWN article with in depth comparisons of the two, for all our exciting cluster needs.

Here's the linecount of both of them:

   GFS2: 26954 lines of code
   +DLM: 11939 lines of code (generic lock manager)
       = 38893 lines of code

  ocfs2: 44952 lines of code (integrated lock manager)

So in that metric, GFS2 is simpler. It has also been cleaned up significantly and the code is very much "Linux-like".

In any case, more in-upstream-kernel filesystem competition is good and Linux can only win as a result :-)
