Subject: [PATCH 01/28] libfc: fix slowpath error from WARN_ON in fc_fcp_send_data
Date: Tue, 20 Jul 2010 15:19:10 -0700 [thread overview]
Message-ID: <20100720221910.17116.28671.stgit@localhost.localdomain> (raw)
In-Reply-To: <20100720221904.17116.78553.stgit@localhost.localdomain>
From: Yi Zou <yi.zou@intel.com>
This is exposed by a mpio test using EMC CLARiiON targets when LUN
tresspassing happens, the burst length from the XFER_READY for the
MODE SELECT(10) is 19 bytes, much smaller than FC_MIN_MAX_PAYLOAD as
256 bytes. This patch removes the related two WARN_ON()s.
