From 33c44184991ec38e637cc4021e3b5e7d2288cea5 Mon Sep 17 00:00:00 2001 From: Josef Bacik Date: Fri, 18 Feb 2022 14:56:11 -0500 Subject: [PATCH] btrfs: pass btrfs_fs_info for deleting snapshots and cleaner We're passing a root around here, but we only really need the fs_info, so fix up btrfs_clean_one_deleted_snapshot() to take an fs_info instead, and then fix up all the callers appropriately.
