Chuck Lever 2fad659209 xprtrdma: Wait on empty sendctx queue ... Currently, when the sendctx queue is exhausted during marshaling, the RPC/RDMA transport places the RPC task on the delayq, which forces a wait for HZ >> 2 before the marshal and send is retried. With this change, the transport now places such an RPC task on the pending queue, and wakes it just as soon as more sendctxs become available. This typically takes less than a millisecond, and the write_space waking mechanism is less deadlock-prone. Moreover, the waiting RPC task is holding the transport's write lock, which blocks the transport from sending RPCs. Therefore faster recovery from sendctx queue exhaustion is desirable. Cf. commit 5804891455d5 ("xprtrdma: ->send_request returns -EAGAIN when there are no free MRs").
