As per Maksym's comments, this has been fixed some time ago.

Thomas, exactly filling of empty file works. But I'm going to close this bug when all errors I find in tmpfs will be fixed. Just to not open new bugs.

Maksym, is this fixed already? If yes, please set to Status: Fixed, and Open/Closed: Closed.

More importantly, that makes the defpager crash:

/hurd/mach-defpager: panic: memory_object_lock_request: 268435459
