This pull request includes a number of patches that didn't quite make the cut last merge window while we addressed some outstanding issues and review comments. It includes some new caching modes for those that only want readahead caches and reworks how we do writeback caching so we are not keeping extra references around which both causes performance problems and uses lots of additional resources on the server. It also includes a new flag to force disabling of xattrs which can also cause major performance issues, particularly if the underlying filesystem on the server doesn't support them. Finally it adds a couple of additional mount options to better support directio and enabling caches when the server doesn't support qid.version. There was one late-breaking bug report that has also been included as its own patch where I forgot to propagate an embarassing bit-logic fix to the various variations of open. Since that was only added to for-next a week ago, if you would like to not include it, I can include it in the first round of fixes for -rc2.
