Subjectwhy does udev set timeout for all SCSI devices?
Hello, Kay.

As the $SUBJ says, why does udev set timeout for all SCSI devices?
It's the following two rules.

50-udev-default.rules:SUBSYSTEM=="scsi", KERNEL=="[0-9]*:[0-9]*",
ACTION=="add", ATTR{type}=="0|7|14", ATTR{timeout}="60"
50-udev-default.rules:SUBSYSTEM=="scsi", KERNEL=="[0-9]*:[0-9]*",
ACTION=="add", ATTR{type}=="1", ATTR{timeout}="900"
The appropriate default timeout differs depending on the transport and
the type of the attached device, so the above two rules harm more than
help. The affect of the above two rules weren't visible for some
reason but with recent block layer timeout update, they actually work
and cause problems.

Thanks.
