A stated there is nothing Wine can do about this. Don't use this FS with Wine.
mmap with shared write can not be emulated. It have to be provided by the file
system & kernel.

says that this kernel/fuse feature is being worked on, see
http://kerneltrap.org/Linux/Fuse_Writable_Mmap

Changing resolution to INVALID to better reflect the fact that
the bug is in a system component, not in wine.
