from what I can see, the  fallocate  issue will affect all distros with kernel 5.7 (till a general patch is available) and thus why it is already affecting archlinux. 

https://bugzilla.kernel.org/show_bug.cgi?id=207585

to be honest, I would suggest to completely move away from fallocate and only use dd  but at least an alternative should be provided for affected distros. 

What do you think ?
