There are other reports of tools, which utilize 'statfs()' call to
monitor available space, also get affected.

So to be more accurate, any tools utilizing 'statfs()' call would
reports false ENOSPC error.

Since you're using arch, and if you're not utilizing bleeding edge
hardware, you could try lts kernel, or at least downgrade to v5.3 and
wait for the fix to be merged and backported.
