Hi David,
i did a git bisect and the breaking commit is:
commit c30da2e981a703c6b1d49911511f7ade8dac20be

fuse: convert to use the new mount API
Convert the fuse filesystem to the new internal mount API as the old
one will be obsoleted and removed. This allows greater flexibility in
communication of mount parameters between userspace, the VFS and the
filesystem.
See Documentation/filesystems/mount_api.txt for more information.

most probably due to the following diffences:
old default:
default:
- return 0;
new default:
+ default:
+ return -EINVAL;
it seems the old API silently did ignore unknown parameters while the
new one fails with EINVAL.
I'm not sure who to blame here but this seems to break existing usespace
fuse programs or may be libfuse 2.9.X in general.
Greets,
Stefan
