@Leann: Perhaps it's too late now, I should've double checked the moment you were replying: you're saying that the *_FSCACHE modules cannot be enabled in an Ubuntu kernel, because they depend on EXPERIMENTAL. While I'm currently trying to convince[0] upstream to remove the EXPERIMENTAL flag from NFS_FSCACHE, I just noticed that both CONFIG_FSCACHE and CONFIG_CACHEFILES is already enabled in Karmic - which are both marked EXPERIMENTAL (since CACHEFILES depends on FSCACHE).

So, I just have to ask: how comes?

From looking at a Karmic config (2.6.31-20-server) I can see that there are other options, which are enabled as well, despite the fact that they depend on EXPERIMENTAL.

Also, Ubuntu is currently shipping the userspace cachefilesd daemon - which is unusable, without the proper kernel support.

So, if anyone from the kernel team reads this - please reconsider and enable the missing *_FSCACHE options.

Thanks,
Christian.
