Description:

I cannot enable zcache/cleancache.

I have added the zcache parameter to kernel command line and also added zcache to initramfs. Dmesg indicates that zcache loads:

[code]
$ dmesg | grep zcache
[ 0.000000] Command line: root=/dev/sda5 rootfstype=ext4 rootflags=data=writeback ro zcache vga=775
[ 0.000000] Kernel command line: root=/dev/sda5 rootfstype=ext4 rootflags=data=writeback ro zcache vga=775
[ 0.501135] zcache: module is from the staging directory, the quality is unknown, you have been warned.
[/code]

However, a working cleancache/zcache would also log lines like these (found in multiple places on the web):

[code]
zcache: cleancache enabled using kernel transcendent memory and compression buddies
zcache: created ephemeral tmem pool, id=0
zcache: created ephemeral tmem pool, id=1
[/code]

There is nothing else in the logs, and of course cleancache is not working.


Additional info:
* package version(s)
