The description of thix patch says:
"Although the one-size-fit-all solution is quite safe, it's too strict if
data and metadata has different duplication level."
...
"This patchset will introduce a new per-chunk degradable check for btrfs,
allow above case to succeed, and it's quite small anyway."
My raid1 is "-m raid1 -d raid1". Both the same duplication level. Would that patch make any difference?
And: What do I need to do to test this in "debian stable"? I am not a programmer - but I know how to use git and how to compile with proper configuration directions.
