Will do, once fuse gets converted.

And fuse will get converted, when I manage to decide on the best way to do it:

1) keep a list of open files for each inode, pick random one for doing
the ioctl (really shouldn't matter which one)

2) do a sequence of open - [sg]et attr - release for each invocation

Thanks,
