In v3.12 'btrfs_delayed_tree_ref' was split in 2 tracepoints and the
name was kept as an event class which did not trigger a build failure.
See upstream commit:
commit 599c75ec3f7f3b606e8a0a684c00f12190712de8

Btrfs/tracepoint: update delayed ref tracepoints
This shows exactly how btrfs processes the delayed refs onto disks,
which is very helpful on understanding delayed ref mechanism and
debugging related bugs.
