Detailed Description

This is a deprecated data structure that only exists for dealing with file systems create prior to ZPL version 5.

Data may pad out any remaining bytes in the znode buffer, eg:

 
  |<---------------------- dnode_phys (512) ------------------------>|
  |<-- dnode (192) --->|<----------- "bonus" buffer (320) ---------->|
 			|<---- znode (264) ---->|<---- data (56) ---->|
 
 

At present, we use this space for the following:

• symbolic links
• 32-byte anti-virus scanstamp (regular files only)
