It's infrastructure for network filesystems.

The original impetus was hooking up fscache, though the helper code also
works with fscache disabled. We also have some work in progress to plumb
in fscrypt support, and David is also looking at adding
writepage/writepages support too.

readpage/readpages/writepage/writepages operations in network
filesystems are quite "fiddly", and they all do it in subtly different
ways (and not always for good reasons).

The new read helper infrastructure abstracts a lot of that away, and
gives netfs's a simpler set of operations to deal with. We're hoping to
do the same with writepage/writepages helpers soon.
