I applied patch #1. #2 had conflicts, please rebase.
Thanks!

Some of these smelled more like features than bug fixes. So I applied
the series to 4.21/scsi-queue.

Steffen,
As I said, I don't have a problem with having module parameters.

The pscsi_set_inquiry_info() and emulate_model_alias_store() codepaths
don't currently explicitly null-terminate t10_wwn.model.
Add an extra byte to the t10_wwn.model buffer and perform null string
termination in all cases.
dev_set_t10_wwn_model_alias() continues to truncate at the same length
to
From: Bart Van Assche
The existing for loops step over null-terminators for right-padding.
Padding can be achieved in a much simpler way using printf width
specifiers.

This patchset allows for the modification of the T10 Vendor
Identification string returned in the SCSI INQUIRY response, via the
target/core/$backstore/$name/wwn/vendor_id ConfigFS path.
Changes since v3:
- perform explicit null termination of t10_wwn vendor, model and
revision fields.
