Subject: Introduce own timeout for TEST_UNIT_READY
|
||
|
|
Reference: SUSE41689
|
||
|
|
Patch-mainline: not yet
|

|
|
In error recovery, a SCSI device may need more than the 10s SENSE_TIMEOUT
|
||
|
|
to respond to TEST_UNIT_READY, as reported in novell bugzilla #56689.
|
||
|
|
The patch introduces an own timeout for TEST_UNIT_READY which is set
|
||
|
|
to 30s and used.
