Subject: [PATCH 02/02] RDMA/nes: listener destroyed during loopback setup crash
Date: Fri, 12 Feb 2010 13:57:04 -0600 [thread overview]
Message-ID: <20100212195704.GA71688@flatif-MOBL> (raw)
When listener is destroyed and where is MPA response pending for
loopback connection, the active side cm_node gets destroyed in
cm_event_connect_error() and again in nes_accept()/nes_reject().
Incrementing cm_node's refcount to not be destroyed by cm_event_connect_error().
