Bruce, I feel this patch set is ready for inclusion.
v2:
1) Rebase on Bruce's "for-3.6" branch.
This patch set makes grace period and hosts reclaiming network namespace
aware.
On a quick skim--yes, that looks reasonable to me.
It doesn't help with active/active cluster exports, because in that case
we need some additional coordination between nfsd's.
But it looks good enough to handle the case where each filesystem is
exported from at most one server at a time, which is more than we
currently handle.
It's a little late for 3.6. Also I get the impression Al Viro has some
lockd rework in progress, which we may want to wait for.
So I'll likely look again into queueing this up for 3.7 once 3.6-rc1 is
out.
Ok.
Will Al Viro's lockd rework be a part of 3.6 kernel?
--b.
Main ideas:
1) moving of
unsigned long next_gc;
unsigned long nrhosts;
struct delayed_work grace_period_end;
struct lock_manager lockd_manager;
struct list_head grace_list;
to per-net Lockd data.
2) moving of
struct lock_manager nfsd4_manager;
to per-net NFSd data.
3) shutdown + gc of NLM hosts done now network namespace aware.
4) restart_grace() now works only for init_net.
The following series implements...
