* libbtrfsutil: add qgroup inheritance helpersOmar Sandoval2018-02-24
| | | | | | | | | | We want to hide struct btrfs_qgroup_inherit from the user because that comes from the Btrfs UAPI headers. Instead, wrap it in a struct btrfs_util_qgroup_inherit and provide helpers to manipulate it. This will be used for subvolume and snapshot creation.

* Add libbtrfsutilOmar Sandoval2018-02-24
Currently, users wishing to manage Btrfs filesystems programatically have to shell out to btrfs-progs and parse the output. This isn't ideal. The goal of libbtrfsutil is to provide a library version of as many of the operations of btrfs-progs as possible and to migrate btrfs-progs to use it. Rather than simply refactoring the existing btrfs-progs code, the code has to be written from scratch for a couple of reasons: * A lot of the btrfs-progs code was not designed with a nice library API in mind in terms of reusability, naming, and error reporting. * libbtrfsutil is licensed under the LGPL, whereas btrfs-progs is under the GPL, which makes it dubious to directly copy or move the code. Eventually, most of the low-level btrfs-progs code should either live in libbtrfsutil or the shared kernel/userspace filesystem code, and btrfs-progs will just be the CLI wrapper. This first commit just includes the build system changes, license, README, and error reporting helper. Signed-off-by: Omar Sandoval <> Reviewed-by: Liu Bo <> Signed-off-by: David Sterba <>
