[PATCH RESEND dlm/next 0/8] dlm: pending fixes based on v7.3-rc1

[Alexander Aring <aahringo@redhat.com>]

Hi David,

this patch series contains pending fixed for dlm.

Some critical to be ensure that monitor/plock chardevs are only be
opened under administrator rights which should be as e.g. dlm_controld
is using them running as root and can conflict with additional multiple
usages. To forbid any misusage we forbid to open those devices for
normal users.

Then we switch back to rhashtables to dynamic key lengths as this might
get conflicts for DLM users who actually using different resource name
lengths in DLM.

Additional malformed packets drops to avoid kernel crashes, however we
still cannot recover from those drops but this is another problem.

Then there are missing barriers for srcu as call_srcu() uses the srcu
static structures which can end in an use after free when the module is
removed.
