DLM Project Page


This is a distributed lock manager (dlm) that we'd like to see added to the kernel. The dlm programming api is very similar to that found on other operating systems, but this is modeled most closely after that in VMS.

Many distributed/cluster applications use a dlm for inter-process synchronization where processes may live on different machines. (GFS and CLVM are two examples which our group also develop; GFS using the dlm from the kernel and CLVM from userspace.)
