commit 05e9ebbefb379a4da782b21b8427c88ac28a2334 Author: Sumant Patro <sumant.patro> Date: Thu May 17 05:47:51 2007 -0700 [SCSI] megaraid_sas: intercept cmd timeout and throttle io eh_timed_out call back (megasas_reset_timer) is used to throttle io to the adapter when it is called the first time for a scmd. The MEGASAS_FW_BUSY flag is set and can_queue reduced to 16. The can_queue is restored from completion routine in following two conditions : 5 seconds has elapsed and the # of outstanding cmds in FW is < 17.
