[Libguestfs] [PATCH v2 0/5] btrfs support part1: subvolume commands

Hi,

This is the part1 of improving btrfs support. This series adds missing
parameters to btrfs_subvolume_snapshot and btrfs_subvolume_create, and
adds two new API btrfs_subvolume_get_default and btrfs_subvolume_show.

Other parts will follow.

Regards,
Hu

changes:
v2:
  - add 'once_had_no_optargs = true' for btrfs_subvolume_snapshot and
    btrfs_subvolume_create
  - improved documents for btrfs_subvolume_snapshot and
    btrfs_subvolume_create
  - coding style change (patch 5)
  - add analyze_line (patch 5)
  - rebase


Hu Tao (5):
  btrfs: add optional parameter `ro' to btrfs_subvolume_snapshot
  btrfs: add optional parameter `qgroupid' to btrfs_subvolume_snapshot
  btrfs: add optional parameter `qgroupid' to btrfs_subvolume_create
  New API: btrfs_subvolume_get_default
  New API: btrfs_subvolume_show
