Do you think we could be successful in patching up the GFS2/DLM modules in our 2.6.21 kernel to bring it up to a more recent version? How coupled is the GFS2/DLM code to the rest of the kernel? We have a number of machines running CentOS 5.1. Does it seem feasible to select the applicable patches from that distribution and apply them to a 2.6.21 kernel (with some tweaks no doubt)?
