Merge tag '9p-6.4-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/ericvh/v9fs
Pull 9p updates from Eric Van Hensbergen:
"This 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"
