Subject: Re: [REGRESSION] 28676d869bbb (scsi: sg: check for valid direction before starting the request) breaks mtx tape library control
Date: Tue, 18 Jul 2017 12:33:59 -0500	[thread overview]
Message-ID: <ufak235abug.fsf@epithumia.math.uh.edu> (raw)
In-Reply-To: <20170718073747.GD4875@linux-x5ow.site> (Johannes Thumshirn's message of "Tue, 18 Jul 2017 09:37:47 +0200")

I have verified that building a clean v4.12 with
68c59fcea1f2c6a54c62aa896cc623c1b5bc9b47 cherry picked on top still
shows the problem:

[root@backup2 ~]# mtx -f /dev/sg7 next 0
Unloading drive 0 into Storage Element 45...mtx: Request Sense: Long
Report=yes
mtx: Request Sense: Valid Residual=no
mtx: Request Sense: Error Code=0 (Unknown?!)
mtx: Request Sense: Sense Key=No Sense
mtx: Request Sense: FileMark=no
mtx: Request Sense: EOM=no
mtx: Request Sense: ILI=no
mtx: Request Sense: Additional Sense Code = 00
mtx: Request Sense: Additional Sense Qualifier = 00
mtx: Request Sense: BPV=no
mtx: Request Sense: Error in CDB=no
mtx: Request Sense: SKSV=no
MOVE MEDIUM from Element Address 1 to 1045 Failed

Nothing appears to be logged; is there any kind of debugging information
I can collect which might help to track this down?  I'm not particularly
good at this but I am pretty sure that I'm building everything properly
and am actually booting the patched kernel.
