71 FS-Cache does not follow the idea of completely loading every netfs file
73 then serving the pages out of that cache rather than the netfs inode because:
87 It instead serves the cache out in chunks as and when requested by the netfs

101 * The interface to the netfs returns as few errors as possible, preferring
102 rather to let the netfs remain oblivious.
106 to the netfs; the netfs gets a volume cookie to represent a collection of
107 files (typically something that a netfs would get for a superblock); and
