Well, I use headers from recent RHEL6 kernel (131.6.1.el6). 

Is that fixed in newer RHEL6 kernels or what kernel version do you suggest?

You need kernel from RHEL6.2.

Are there known bugs with 131.6.1.el6 (rhel6.2 is still beta)?

I am not sure I understand the question... kernel is kind of big and a
query in bugzilla.redhat.com will answer your question too :)

You suggested to use another kernel, so I thought you are aware of a specific bug related to old dlm_plock.c as used in  131.6.1.el6?

The new kernel has a plock fix that the old one does not have. Unless
you are using posix locks, it doesn?t affect you.

You need a new kernel to build the userland counterpart without workaround.

Seems I can just cherry pick the fix from:

http://git.kernel.org/?p=linux/kernel/git/stable/linux-3.0.y.git;a=commitdiff;h=901025d2f3194b4868980c8ba80df4cc0aa1282c

So far that seems to work.

Compile is broken after that patch. I get:

/cluster-3.1.5/group/dlm_controld/plock.c:744:2: warning: #warning DLM_PLOCK_FL_CLOSE undefined. Enabling build workaround.
/cluster-3.1.5/group/dlm_controld/plock.c: In function \u2018process_plocks\u2019:

I pushed a workaround for this, but you need to update your kernel headers.
