Public bug reported: Binary package hint: cachefilesd
Hello, In #440522 i reported that NFS and AFS modules were not compiled into the kernel, so caching NFS was not possible with cachefilesd. I build my own kernel on the Ubuntu sources with these modules enabled and started testing. The modules load fine and everything seems OK until the caching starts, this is what comes up in the dmesg.
