To actually use it, we first have to copy symbols over from the dlm build into the scoutfs source directory. Make that happen automatically for us in the Makefile. The only users of locking at the moment are mount, unmount and xattr read/write. Adding more locking calls should be a straight-forward endeavor. The LVB based server ip communication didn't work out, and LVBS as they are written don't make sense in a range locking world. So instead, we record the server ip address in the superblock. This is protected by the listen lock, which also arbitrates which node will be the manifest server. We take and drop the dlm lock on each lock/unlock call. Lock caching will come in a future patch.
