| | | | | | | | | | | | | | | | | | | twice. - in case of failure to send message, ioq-entry would be freed, but it used to get added to the ioq-list. Failure in sending a message (for reasons other than insufficient quota), would result in transport being disconnected. In the process of handling pollerr, when ioq-list is flushed, the same ioq-entry which would've already been freed, would be freed for second time. - this patch also fixes spurious disconnects happening when quota was not available while sending a request.

* rpc/rpc-transport: fix frame-loss during rdma-reads.v3.1.0qa31Raghavendra G2010-09-242-3/+18
| | | | | | | | | | | | | | | | | | - total no of rdma reads in progress was tracked using refcount of post (refcount = total rdma reads + 1). However doing rdma_post_unref _after_ rdma_do_reads, can result in race condition between execution of rdma_post_unref and procedure handling rdma read completion. This makes it impossible to find out whether the current rdma read was the last rdma-read being done in procedure handling rdma read-completion. The fix to this should either do rdma_post_unref before posting an rdma read or use another variable to track the number of rdma-reads. This patch implements second method.
