[DragonFlyBSD - Bug #2404] cp from dir mounted with mount_psshfs fails on mmap -1 errno 22 Invalid argument

[Max Herrgard via Redmine]

Issue #2404 has been updated by Max Herrgard.


And cp still gets an empty file there.. not sure if that is important to know.

zoidberg# file tmp/README 
tmp/README: empty

This cp issue is also hit using filesystems/fuse-mp3fs from pkgsrc.
