scsi: target: core: Add CONTROL field for trace events
[ Upstream commit 7010645ba7256992818b518163f46bd4cdf8002a ]
trace-cmd report doesn't show events from target subsystem because
scsi_command_size() leaks through event format string:
[target:target_sequencer_start] function scsi_command_size not defined
[target:target_cmd_complete] function scsi_command_size not defined
Addition of scsi_command_size() to plugin_scsi.c in trace-cmd doesn't
help because an expression is used inside TP_printk(). trace-cmd event
parser doesn't understand minus sign inside [ ]:
Error: expected ']' but read '-'
Rather than duplicating kernel code in plugin_scsi.c, provide a dedicated
field for CONTROL byte.
