Thanks,
I've applied this patch to the core-for-3.19 branch after fixing a few
whitespace issues.

Hello Kai
You have seen this patch before. The first time around, given that we don't
enable DEBUG by default, I let it go.
However we have been looking into defining DEBUG 1 by default here at Redhat
and then setting the default to disabled.
Are you open to considering changing the driver base
Are ANSI-formatted tapes used on Linux? That is, tapes that contain
multiple files and use the the ANSI (= ECMA-13) tape labels. My
uderstanding is that a lot of the modern cartridge tapes record only
fixed-length blocks and/or that is how they are always used these
days.

Kai,
Thank you for considering this.
With #define DEBUG 0
We still include
#define DEB(a)
#define DEBC(a)
With the debug_flag we then provide the needed debug I am looking for at module
load time.
This thread leads me to ask: Do people use ANSI-formatted tapes any
more? That is, tape volumes with miltiple files, header and trailer
labels, etc.?

Hello
Take 2 of this patch, changed module description and subject line.
This patch adds a debug_flag parameter that can be set on module load, and
allows the DEBUG facility without a module recompile.
Usage: mpdprobe st debug_flag=1

Hello
I am tired of building modules to enable SCSI tape driver debug so I am hoping
this patch is acceptable.
Tested using kernel 3.14.6
Usage example:
modprobe st debug_flag=1
