Neuter fuse_vptofh() and fuse_fhtovp(). I implemented those functions
under the assumption, that fuse_vget() has reasonable semantics, while
this is not the case. fusefs_vget() only functions correctly, if the
file in questions has recently been accessed and is still in the vnode
cache of the userspace daemon associated with the mount point.
As a matter of fact the fuse api doesn't feature a reasonable way to map
inode numbers to a handle at all (see struct fuse_operations).
