I have run this through our production workloads without issue. There
were no recorded performance or stability differences between this and
the old fscache/cachefiles.

Our workload comprises mounting ~20 remote servers with "-o fsc" over
the WAN and then re-exporting those to 500 local client instances.
This production workload churns the fscache backing filesystem (EXT4)
pretty well (hundreds of MB/s) across all of the mount points
simultaneously.

I tested with both NFSv4.2 and NFSv3 mounts. Previously written cache
data was correctly reused between reboots and remounts.
