This patch is to do write back throttling for cache tiering,
which is similar to what the Linux kernel does for
page cache write back. The motivation and original idea are
proposed by Nick Fisk, detailed in his email as below. In our

This is a new feature of rbd layering, when reading an object
from child, if not exist, the kernel rbd client will not only
request parent for the object, but also write it to child,
and the jobs are done in an asynchronous way. Therefore, the
subsequent accesses on this object will hit child
a slave. For example, in Step 3, the master also will
check if there is a conflict in-flight transaction.

zero_user_segment() has invoked flush_dcache_page() for us, we donnot

If the length of data to be read in readpage() is exactly
PAGE_CACHE_SIZE, the original code does not flush d-cache
for data consistency after finishing reading. This patches fixes
this.

Currently, the page allocated into fscache in readpage()
for Cifs and Ceph does not be uncached if no data read due
to io error. This patch fixes this. fscache_readpages_cancel()
is for this kind of job but taking list read * as input, so
a new routine take page * as input is introduced.
