[PATCH v2 0/2] delayed_node leak bug

[Leo Martins <loemra.dev@gmail.com>]

Currently investigating a bug I believe is caused by leaked
delayed_nodes. The following patches fix a potential delayed_node leak
in an assert function (I don't believe this is the cause of the bug) and
add a warning if a root still contains delayed_nodes when it is freed.

A little more on the bug I'm investigating in case anyone has seen
something similar...

Started seeing soft lockups in btrfs_kill_all_delayed_nodes due to an
infinte loop. Further investigation showed that there was a
delayed_node that was not being erased from the root->delayed_nodes xarray.
The delayed_node had a reference count of one meaning that it is failing
to be released somewhere.

V2 CHANGES:
- combine warn and if statement

Leo Martins (2):
  btrfs: fix refcount leak in debug assertion
  btrfs: warn if leaking delayed_nodes
