compcache: Decompression fails during suspend/resume

[GoogleCodeExporter]

What steps will reproduce the problem?
1. Engage compcache with some memory intensive tasks
2. Suspend to RAM
3. Resume from RAM. Some of the times, compcache decompression fails and
one of the big memory hog process (usually firefox-bin) will die.

What is the expected output? What do you see instead?
Resume should proceed without errors and there should be no swap-in errors.

What version of the product are you using? On what operating system?
compcache-0.4, 2.6.26.3, x86_64

Please provide any additional information below.

[117068.638333] Read-error on swap-device (252:0:749672)

Can you please check if this issue is still present in compcache-0.5.1?

This happened may be couple of times. So, its not really a reproducible bug. I 
have
just moved to 0.5.1. I would like to keep this bug open for few weeks to see if 
I
ever hit it again.

Do we have enough stats in place that we can catch it when it happens next?

Not really - no extra code instrumentation to catch it better. But if this 
happens
again, we can surely add some debugging :)

devsku: please reopen if you hit this again.

... and here goes another victim of my bug closing spree :)
