I believe it's possible to use DLM as a general-purpose lock manager.

	hi all,
	my first post on this list.  say, ive been checking out dlm a
little bit lately.  we are trying to build (or leverage) a distributed
lock to manage access to files mounted via nfs.  some of the folks here
are telling me that dlm is not suitable for this, however, my suspicion
is that the dlm is independent of a filesystem.  is this accurate?  for
example i imagine the code could ask for a lock on a given resource, and
then if it acquires a write lock, modify the file.  am i way off base
here?  just trying to get my footing before investing too much time in
the wrong approach...
