What Neil Brown refers to as a "general file access protocol" -
basically making a flash disk available to a small embedded network for
random-access file I/O.

The flash disk is required to interoperate with Windoze, which forces us
into VFAT-backed NFS.

We use lookupcache=none, which I thought had stabilized things. Based on
what Namjae has found with ESTALE on rename/drop_caches I guess there is
a hole.
