Default mkfs. Default mount options.

However, due to subsequent suboptimal situation (installing Windows 10
after Fedora), this Btrfs volume is actually a two device volume: two
partitions with Windows 10 in between them.

p4 was made to small when adding in Windows; so I shrank Windows to
make p6, and then added p6 to p4. Hence p4 and p6 are the same Btrfs
volume (single profile for metadata and data).
