[Ocfs2-devel] [PATCH] ocfs2: cancel nn_still_up work when connection came up

[Xue jiufei]

We found that ocfs2 doesn't cancel the nn_still_up delayed work when
connection comes up. So if a node lost its connectivity and after a
while (more than idle time) the connection came up, it would still
make the quorum decision which we don't expect. And worse still, it
may result in an error of judgment if node detected another
connectivity lost just before the decision.
