[PATCH 1/9] scsi: move initialization of scmd->eh_entry

The 'eh_entry' list might be used even before scsi_softirq_done() is called. Hence we should rather initialize it together with the other eh-related variables. Signed-off-by: Hannes Reinecke --- drivers/scsi/scsi_lib.c | 4 ++-- 1 file changed, 2 insertions(+), 2 deletions(-) diff --git a/drive

[PATCH 3/9] scsi: improved eh timeout handler

When a command runs into a timeout we need to send an 'ABORT TASK' TMF. This is typically done by the 'eh_abort_handler' LLDD callback. Conceptually, however, this function is a normal SCSI command, so there is no need to enter the error handler. This patch implements a new scsi_abort_command() f

[PATCHv2 0/9] New SCSI command timeout handler

this is the first step towards a new non-blocking error handler. This patch implements a new command timeout handler which will be sending command aborts inline without engaging SCSI EH. In addition the commands will be returned directly if the command abort succeeded, cutting down recovery times
