Subject[PATCH RFC 00/13] Lockd: grace period containerization
From
Date
This patch set is marked with RFC, because I'm still not quite sure, that this
implementation will satisfy other interested people.
So, would be appreciated for any comments.

This patch set makes grace period and hosts reclaiming network namespace
aware.

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...

Stanislav Kinsbursky (13):
LockD: mark host per network namespace on garbage collect
LockD: make garbage collector network namespace aware.
LockD: manage garbage collection timeout per networks namespace
LockD: manage used host count per networks namespace
Lockd: host complaining function introduced
Lockd: add more debug to host shutdown functions
LockD: manage grace period per network namespace
LockD: make lockd manager allocated per network namespace
NFSd: make nfsd4_manager allocated per network namespace context.
SUNRPC: service request network namespace helper introduced
LockD: manage grace list per network namespace
LockD: pass actual network namespace to grace period management functions
Lockd: move grace period management from lockd() to per-net functions
