Precise 3.2 fscache

Hi there,

please apologize if this list is the wrong place for my request.

Precise's linux-image-virtual aka linux-image-3.2.0-25-virtual has CONFIG_FSCACHE=m and CONFIG_CACHEFILES=m
Due to CONFIG_NFS_FSCACHE=y it's usable on NFS mounts.
Is there a reason for not setting CONFIG_CIFS_FSCACHE ?
I'ld really like to get the benefits of fscache on CIFS mounts by using ubuntu's mainline kernel.
So, I'ld like to ask if it would be possible to alter the build configuration to CONFIG_CIFS_FSCACHE=y ?

Cheers,

CONFIG_CIFS_FSCACHE depends on EXPERIMENTAL. Our default policy is to
_not_ enable experimental features unless we've determined prior to
release that its a beneficial feature and relatively mature.
