Re: regression: SCSI/SATA failure

[Thorsten Leemhuis]

JFYI: This issues is tracked in the regression reports for Linux 4.16
(http://bit.ly/lnxregrep416 ) with this id:

Linux-Regression-ID: lr#15a115

Please include this line in the comment section of patches that are
supposed to fix the issue. Please also mention the string once in other
mailinglist threads or different bug tracking entries if you or someone
else start to discuss the issue there. By including that string you make
it a whole lot easier to track where an issue gets discussed and how far
patches to fix it have made it. For more details on this please see
here: http://bit.ly/lnxregtrackid

Thx for your help. Ciao, Thorsten
