[GIT PULL 14/18 for v7.3] vfs netfs

[Christian Brauner]

Hey Linus,

/* Summary */

This sunsets cachefiles ondemand mode. It was an effort to make fscache
usable as a kernel cache for lazy pulling. EROFS over fscache was its
only in-tree user. fscache has since become netfslib-oriented while
EROFS never acts as a network filesystem and EROFS over fscache has been
removed. So this cleans up the netfs, fscache and cachefiles side as
well.

/* Testing */

No build failures or warnings were observed.
