From mboxrd@z Thu Jan 1 00:00:00 1970 From: Anish Bhatt Subject: [PATCH net] cxgb4i : Don't block unload/cxgb4 unload when remote closes TCP connection Date: Tue, 18 Nov 2014 19:09:51 -0800 Message-ID: <1416366591-9699-1-git-send-email-anish@chelsio.com> Cc: linux-scsi@vger.kernel.org, davem@davemloft.net, hch@infradead.org, jbottomley@parallels.com, kxie@chelsio.com, manojmalviya@chelsio.com, Anish Bhatt To: netdev@vger.kernel.org Return-path: Sender: linux-scsi-owner@vger.kernel.org List-Id: netdev.vger.kernel.org cxgb4i was returning wrong error and not releasing module reference if remote end abruptly closed TCP connection. This prevents the cxgb4 network module from being unloaded, further affecting other network drivers dependent on cxgb4 Sending to net as this affects all cxgb4 based network drivers.
