Hi, This series adds support to btrfs qgroup related commands, inclduing quota commands, and two leftover of subvolume commands. Regards, Hu Hu Tao (8): New API: btrfs_subvolume_get_default New API: btrfs_subvolume_show New API: btrfs_quota_enable New API: btrfs_quota_disable New API: btrfs_quota_rescan New API: btrfs_qgroup_limit New API: btrfs_qgroup_create New API:

Hi, This is v3 series to add support to btrfs qgroup related commands, inclduing quota commands, and two leftover of subvolume commands. Regards, Hu changes: v3: - don't intialize fs_buf (patch 1) - check the return value of sysroot_path (patch 1) - check fs_buf rather than fs (patch 1) - fprintf (stderr,...) -> reply_with_error() v2: - add tests for new APIs - combine

This is just the utilities part of the patch series from: https://www.redhat.com/archives/libguestfs/2017-June/msg00103.html I believe this addresses everything raised in comments on that patch series. Rich.

This turned out to be rather more involved than I thought. We have lots of utility functions, spread all over the repository, with not a lot of structure. This moves many of them under common/ and structures them so there are clear dependencies. This doesn't complete the job by any means. Other items I had on my to-do list for this change were: - Split up mllib/common_utils into: -
