bug: btrfs_commit_transaction: at fs/btrfs/extent-tree.c:2159 btrfs_run_delayed_refs

[Chris Murphy]

kernel 5.17.5
The reporter says it happens during boot, but in Fedora we don't have
anything that's doing fs shrink during boot. I'm not seeing anything
in changelogs suggesting this has been fixed in 5.17 stable yet.
