Hi all, this patches set uses the new ioctl BTRFS_IOC_GET_CHUNK_INFO to get information about the chunk (see my other emails).
The first patch change the function get_partition_size() to avoid ioctl which would require root privileges (BLKGETSIZE64). Instead it obtain the information via the sysfs filesystem. The second patch use the BTRFS_IOC_GET_CHUNK_INFO instead of TREE_SEARCH_IOCTL. The old code is still in place as fallback when the kernel doesn't have the new ioctl. These patches allow to use "btrfs fi usage" without root privileges.
