From 177848f09a13950899ef067253af8243866148b7 Mon Sep 17 00:00:00 2001 From: Boris Burkov Date: Thu, 28 Sep 2023 16:16:46 -0700 Subject: btrfs: quota rescan helpers Many btrfs tests explicitly trigger quota rescan. This is not a meaningful operation for simple quotas, so we wrap it in a helper that doesn't blow up quite so badly and lets us run those tests where the rescan is a qgroup detail.
