Have been doing additional testing of these - and also verified that David's most recent patch, now in my for-next branch ("cifs: Fix memory leak in direct I/O") fixes the remaining problem (the issue with xfstest 208 that Murphy pointed out).  Will send the three small cifs fixes from David later this week, along with some unrelated fixes from Paulo and Shyam.

Minimal fix applied - that way I can drop this for now, and we can discuss the whole "maybe we can just use write_cache_pages()" instead.

Because that _would_ be lovely, even if it's possible that the generic helper might need some extra love to work better for cifs/afs.
