Commit c6887cd11149 ("Btrfs: don't do nocow check unless we have to")

the array is built with 5x8TB HDD in an esternal USB3.0 to SATAIII enclosure
The enclosure is a cheap JMicron based chinese stuff (from Orico).
There is one USB3.0 link for all the 5 HDD with a SATAIII 3.0Gb
multiplexer behind it. So y
