SUNRPC: If the rpcbind channel is disconnected, fail the call to unregister

2013-08-07T21:07:18+00:00

If rpcbind causes our connection to the AF_LOCAL socket to close after
we've registered a service, then we want to be careful about reconnecting
since the mount namespace may have changed.

By simply refusing to reconnect the AF_LOCAL socket in the case of
unregister, we avoid the need to somehow save the mount namespace. While
this may lead to some services not unregistering properly, it should
be safe.

SUNRPC: Don't allow low priority tasks to pre-empt higher priority ones

2012-12-05T23:30:53+00:00

Currently, the priority queues attempt to be 'fair' to lower priority
tasks by scheduling them after a certain number of higher priority tasks
have run. The problem is that both the transport send queue and
the NFSv4.1 session slot queue have strong ordering requirements.

This patch therefore removes the fairness code in favour of strong
ordering of task priorities.

SUNRPC: Ensure that we can trace waitqueues when !defined(CONFIG_SYSCTL)

2012-02-15T05:19:51+00:00

The tracepoint code relies on the queue->name being defined in order to
be able to display the name of the waitqueue on which an RPC task is
sleeping.

SUNRPC: Fix potential races in xprt_lock_write_next()

2012-02-01T00:28:08+00:00

We have to ensure that the wake up from the waitqueue and the assignment
of xprt->snd_task are atomic. We can do this by assigning the snd_task
while under the waitqueue spinlock.
