btrfs-progs: mkfs: print the summary
This patch prints the summary of the filesystem after the creation.
The main fileds printed are:
- devices list with their uuid, devid, path and size
- raid profile (dup,single,raid0...)
- leafsize/nodesize/sectorsize
- filesystem features (raid56, extref, mixed-bg)
- chunk size and type
If the '-v' switched is passed, the output is more verbose; if the '-q'
switched is passed, only the errors are printed.
Below an example:
BTRFS filesystem summary:
