A couple of caches were no longer needed:
- iov_iter improvements to orangefs_devreq_write_iter eliminated
the need for the dev_req_cache.
- removal (months ago) of the old AIO code eliminated the need
for the kiocb_cache.
Also, deobfuscation of use of GFP_KERNEL when calling kmem_cache_(z)alloc
for remaining caches.

There were two just alike, making it hard maybe to tell which one
you were looking at in syslog... so I changed it a little by adding
some extra interesting tidbits to it...

Previously, it would update a live inode. This was fixed, but it did not
ever check that the inode attributes in the dcache are correct. This
checks all inode attributes and rejects any that are not correct, which
causes a lookup and thus a new getattr.
Perhaps inode_operations->permission should replace or augment some of
this.
There is no actual caching, and this does a rather excessive amount of
network operations back to the filesystem server.

Orangefs: merge with V4.4
Merge tag 'v4.4' of git://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux into current
Linux 4.4
Until now, orangefs_devreq_write_iter has just been a wrapper for
the old-fashioned orangefs_devreq_writev... linux would call
.write_iter with "struct kiocb *iocb" and "struct iov_iter *iter"
and .write_iter would just:
return pvfs2_devreq_writev(iocb->ki_filp,
iter->iov,
iter->nr_segs,
&iocb->ki_pos);

The reason is that start_shepherd_timer schedules the shepherd work item
which uses vmstat_wq (vmstat_shepherd) before setup_vmstat allocates
that workqueue so if the further initialization takes more than HZ we
might end up scheduling on a NULL vmstat_wq. This is really unlikely
but not impossible.
