* [PATCH 8/9] mpt fusion: error recovery improvements, and synchronizing internal commands
@ 2007-09-18 2:01 Eric Moore

From: Eric Moore @ 2007-09-18 2:01 UTC (permalink / raw)
To: linux-scsi, James.Bottomley
1) cleanup ioc_reset callback handlers, introducing wrappers for synchronizing error recovery (mpt_set_taskmgmt_in_progress_flag, mpt_clear_taskmgmt_in_progress_flag), as the fusion firmware only handles one task management request at a time.
2) rewrite of all internal generated functions that issue commands to firmware, porting them to be single threaded using the generic MPT_MGMT struct.
3) rewrite taskmanagement request and completion routines, making them single threaded and using the generic MPT_MGMT struct, deleting mptscsih_TMHandler, replacing with single request TM handler mptscsih_IssueTaskMgmt, and killing the watchdog timer functions.
4) moving mptscsih_quiesce_raid over from mptspi, using the single threaded internal command changes.
