Just to be complete, the DLM recovery callbacks were introduced in this 
commit

http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/fs/gfs2?id=60f98d1839376d30e13f3e452dce2433fad3060e

GFS2 also supports the older controld using DFL_NO_DLM_OPS flag set in 
the lockspace structure.

While I would also like the controld to be done away with: from a 
maintenance perspective.
