Ok, as I said before, I don't care where you put it, just writting and reading multiple values at once in sysfs files is not to be tolerated. > > > reading of Documentation/filesystems/sysfs.txt indicates that such a usage > > > is "socially acceptable".

Are they socially acceptable? The block device stuff I understand as they want a single snapshot. They also can't create multiple files for every value or the 20,000 disk system admins will complain :) As for the other ones, have specific examples? And none of them are "multiple value write", correct? That, and due to the fact that your implementation will drop needed data is why I object to your patch so much. I'm sure you can understand that desiging in a limitation that could cause data to be dropped that people really want is not a good thing. > > > bonding_masters.

From what I last remember, they either were not able to be applied, or some other trival problem with them. thanks, greg k-h - To unsubscribe from this list: send the line "unsubscribe netdev" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html
