btrfs: snapshot creation with qgroup inherit would mark qgroup inconsistent

mirror of https://github.com/linux-apfs/apfstests.git synced 2026-05-01 15:01:44 -07:00

Test that a new snapshot created with qgroup inherit passed should
mark qgroup numbers inconsistent.

Such inconsistent flag is required to show that we need a qgroup
rescan to make qgroup numbers correct again.

This is unavoidable since snapshot creation with qgroup inherit acts
as snapshot creation + qgroup relationship assign.

See btrfs(5) for why such operation needs qgroup rescan.

This test failed on current kernel, the fix is submitted to the btrfs
mail list titled:

  "btrfs: qgroup: Mark qgroup inconsistent if we're inherting snapshot to a new qgroup"
