lockd_up() can call lockd_unregister_notifiers twice:
inside lockd_start_svc() when it calls lockd_svc_exit_thread()
and then in error path of lockd_up()
Patch forces lockd_start_svc() to unregister notifiers in all error cases
and removes extra unregister in error path of lockd_up().

lockd and nfsd inet[6]addr notifiers use pointer that can be changed during
execution.
lockd_inet[6]addr_event use nlmsvc_rqst without taken nlmsvc_mutex,
nfsd notifier have similar trouble.
We got few crashes from OpenVz customers on RHEL6-based kernel,
and I have reproduced the problem locally

Would this be solved by saying that the rseq api will return an error if you
register and there's already a block registered. In this case the signal
handler would register the rseq abi

Hello, Will,
Good point -- I should have removed that as soon as you posted the
update. I have removed it now.
I am happy to take the patches, but let's make sure that I am up to
speed on the current state and dependencies. Here is my current
scorecard, please double-check:
1. Your patche
lockd_inet[6]addr_event use nlmsvc_rqst without taken nlmsvc_mutex,
nlmsvc_rqst can be changed during execution of notifiers and crash the host.
Patch enables access to nlmsvc_rqst only when it was correctly initialized
and delays its cleanup until notifiers are in use.
NB: this patch depends on
nfsd_inet[6]addr_event use nn->nfsd_serv without taken nfsd_mutex,
pointer can be changed during execution of notifiers and crash the host.
Moreover if notifiers was enabled in one net namespace it will be enabled
in all other net namespaces, from its creation until its destroy.
Patch allows not
