According to this (seemingly 2+ year old) web page, the XFS file system chokes on the combination of 32 bit userland and 64 bit kernel.
Is this still true, and why should a low-level driver hidden under a virtual fs care what user apps access it via the vfs?

XFS as in the plain posix filesystem works perfectly fine with a 64 bit kernel and 32 bit userspace.
But various advance capabilities or administration interfaces which are used by tools from xfsprogs are implemented as ioctls, and unfortunately most of them have been designed very badly and aren't wordsize clean.
There have been handlers for a few of them for a while, but only as of today a full set of compat handlers has been commited. That code will be release with 2.6.29, but could also be backported.
