Please split this into the writeback infrastructure and an XFS patch.
Adding infrastructure and the user in the same patch is really annoying
for bisecting, reverting or even just reading commit logs.

Add more sanity check on node folio during its writeback, if node footer
indicates it is an inode:
- i_mode should be consistent w/ inode
- ofs_of_node should be consistent w/ non-xattr node
In addition, if sanity check fails, let's shutdown filesystem to avoid
looping to redirty and writeback it.

When running the test in a VM on a host with all CPUs busy, the kill command
returns before socket tool shuts down. This prevents unmounting the

The added sleep ensures that the socket tool closes before the next test steps.
