With this patch set Lockd will be able to handle lock requests from different network namespaces separately.
Main ideas of the patch set are:
1) per-net Lockd users counter and resources.
2) nlmsvc_users counter become global one (equal to sum of all per-net counters).
3) On lockd_up() call: a) if nlmsvc_users if equal to 0, then lockd thread is started. b) if current per-net counter equal to 0, then per-net resources are allocated (lockd_up_net() function). c) global and current net users counters are increased by one.
4) On lockd_down() call: a) global and current net users counters are decreased by one. b) if current per-net counter become equal to 0, then per-net resources are allocated (lockd_down_net() function). c) if nlmsvc_users become equal to 0, then lockd thread is stopped.
The following series consists of:
---
