| | | | | | | | | | | | | | | | | | - 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.
