[Ocfs2-users] umount hang + high CPU

That's a quick fix :D

How do I put it in my system?

I have only recently downloaded and upgraded both tools and kernel, so I gather that it is not on the recent version of either. That dlmmaster.c file is not in the tools package, does that mean that this file is in the kernel? Do I need to patch and compile the kernel from the development code? (which is where?)
