Hi all,
This is the 4th attempt of my patches related to show how the data
are stored in a btrfs filesystem. I rebased all the patches on the v3.13
btrfs-progs.
These patches update the btrfs fi df command and add two new commands:
- btrfs filesystem disk-usage path
- btrfs device disk-usage
Enhance the command btrfs filesystem df to show space usage information
for a mount point(s). It shows also an estimation of the space available,
on the basis of the current one used.
