Hi Ric and Christoph,

And as with all previous posting I still fundamentally disagree about
the need of this functionality. We don't need a timeout for freezing.
I agree with Christoph here, I think that the timeout is unneeded.
I think that your concern is that the freezer cannot recognize the occurrence
of a timeout and it continues the backup process and the backup data is
corrupted finally.
If the freezer can recognize it by the unfreeze ioctl's errono, will your concern
be solved?
If so, I will implement it.
Cheers, Takashi
I think that is certainly part a big part of my concern.
Also note that the timeout seems to be quite low relative to say the standard timeout for a SCSI
device (30 seconds worst case).
In general, I am quite supportive of the patch series and think that this is a great addition.
Thank you for your comments.
Christoph, do you have any comments about this solution?
If it's OK, I will change the freeze patch so that the unfreeze ioctl sets
ETIMEDOUT to errno when the timeout occurs.
Cheers, Takashi
