Here's the search results against my running kernel (2.6.19-gentoo-r2).
Symbol: DLM [=n]
Prompt: Distributed Lock Manager (DLM)
Defined at fs/dlm/Kconfig:4
Depends on: INET && IP_SCTP && EXPERIMENTAL && (IPV6 || IPV6=n)
Location:
-> File systems
-> Distributed Lock Manager
Selects: CONFIGFS_FS
Selected by: GFS2_FS_LOCKING_DLM && BLOCK && GFS2_FS
I was unable to find it in my older kernel (2.6.18-gentoo), so perhaps a
kernel upgrade could solve (part of) your issue. Of course, any
out-of-tree modules will have to be compiled after you fix up
your /usr/src/linux symlink. 'module-rebuild' can help with that.
2.6.19-gentoo-r2 also provides:
Symbol: GFS2_FS_LOCKING_DLM [=n]
Prompt: GFS2 DLM locking module
Defined at fs/gfs2/Kconfig:34
Depends on: BLOCK && GFS2_FS
Location:
-> File systems
-> GFS2 file system support (GFS2_FS [=n])
Selects: DLM
Which probably makes sys-cluster/gfs-kernel unecessary, too.

I might look at this, but the easiest way to see if it's in the wrong
location is just find it on the filesystem. (I don't trust the output of
emerge all the time anyway -- some packages do stupid things like ignoring
$ROOT and whotnot.)

Hrm, make sure this is modprobed before gfs tries to load lock_dlm. That
might solve your issue without a kernel upgrade. In my first post, I
didn't consider the fact that you have sys-cluster/dlm-kernel (which
provides the out-of-tree dlm.ko) despite the fact that you mentioned it.
