From ba402804ac2447ad41f4919603bf3e6f6db63110 Mon Sep 17 00:00:00 2001 From: Yi Zou Date: Tue, 20 Jul 2010 15:19:10 -0700 Subject: [SCSI] libfc: fix slowpath error from WARN_ON in fc_fcp_send_data 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.
