* | NLM: Ensure that we resend all pending blocking locks after a reclaimTrond Myklebust2013-02-191-0/+3
|/ | | | | | | | | | | | | Currently, nlmclnt_lock will break out of the for(;;) loop when the reclaimer wakes up the blocking lock thread by setting nlm_lck_denied_grace_period. This causes the lock request to fail with an ENOLCK error. The intention was always to ensure that we resend the lock request after the grace period has expired.

| * Lockd: pass network namespace to creation and destruction routinesStanislav Kinsbursky2012-04-112-9/+11
| | | | | | | | | | | | | | | | | | | | | | | | | | v2: dereference of most probably already released nlm_host removed in nlmclnt_done() and reclaimer(). These routines are called from locks reclaimer() kernel thread. This thread works in "init_net" network context and currently relays on persence on lockd thread and it's per-net resources. Thus lockd_up() and lockd_down() can't relay on current network context. So let's pass corrent one into them. Signed-off-by: Stanislav Kinsbursky <skinsbursky@parallels.com> Signed-off-by: J.

| * Lockd: shutdown NLM hosts in network namespace contextStanislav Kinsbursky2012-02-152-8/+22
| | | | | | | | | | | | | | | | | | Lockd now managed in network namespace context. And this patch introduces network namespace related NLM hosts shutdown in case of releasing per-net Lockd resources.
