In zram_read() and zram_write() we were not incrementing the

Is this something that needs to go into .38 or can it wait until .39?



This really needs to get into .38 or users will see random data
corruption on zram devices.

Ok, I'll queue it up for there. What about .37 and/or .36?



The same problem exists on .37 and .36. I just checked that the same patch applies cleanly to both these version so may be included in their respective maintenance releases.

Thanks,
Nitin
