Do not use "default n" - this is already the default value.

EXTRA_CFLAGS are deprecated in favour of ccflags-y

static const struct scst_sdbops scst_scsi_op_table[] 

This does not belong to a header file.

There was a lot af TRACE_ENTRY() / TRACE_EXIT() noise.
We should have proper tools for that by now (I hope).

We often ask for exported symbols to be documented - so one has
a slight idea of their purpose.

CONFIG_SCST_STRICT_SERIALIZING has bad impact on readability.
Could this be abstracted better?


I did not look into the source in details. Just a few sparse comments.
