CONFIG_ZCACHE=m dies a horrid death:

Thanks Valdis. A fix for this has already been posted by
Nitin Gupta and Randy Dunlap here:

Another patch for a zcache memory leak has been posted here:

I'm sorry that multiple people have run into this in
multiple trees.
I have to admit I am a bit baffled as to what the proper
tree flow is for bug fixes like this, but would be happy
to "follow the process" if I am told what it is or if
someone can point me to a document describing it.

(Clearly making sure there are no bugs at all in a
submission is the best way to go, but I'm afraid
I can't claim to be perfect :-)

When CONFIG_SYSFS is not enabled:

mmotm-2011-0210-1626/drivers/staging/zcache/zcache.c:1608: error: 'ret' undeclared (first use in this function)
