Description

In the Linux kernel, the following vulnerability has been resolved: RDMA/irdma: Fix drain SQ hang with no completion SW generated completions for outstanding WRs posted on SQ after QP is in error target the wrong CQ. This causes the ib_drain_sq to hang with no completion. Fix this to generate completions on the right CQ. [ 863.969340] INFO: task kworker/u52:2:671 blocked for more than 122 seconds.
