This patch adds an subcommand in inspect-internal. It dumps file extents of
the file that user provided. It helps to show the internal information
about file extents comprise the file.

Do you have an example of the output? That's the most interesting part.
Thanks.

Thanks for reply.
This is an example of the output below.

# ./btrfs inspect-internal dump-file-extent /mnt/test1
type = regular, start = 2097152, len = 3227648, disk_bytenr = 0, disk_num_bytes = 0, offset = 0, compression = none
type = regular, start = 5324800, len = 16728064, disk_bytenr = 0, disk_num_bytes = 0, offset = 0, compression = none
type = regular, start = 22052864, len = 8486912, disk_bytenr = 0, disk_num_bytes = 0, offset = 0, compression = none
type = regular, start = 30572544, len = 36540416, disk_bytenr = 0, disk_num_bytes = 0, offset = 0, compression = none
