The remaining functionality in debug.[ch] is effectively just assert handling, conditional debug definitions and hex dumping. The hex dumping and assert function can be moved into the new printk module, while the rest can be moved into top-level header files. This allows fs/xfs/support/debug.[ch] to be completely removed from the codebase.
