Adam D. Moss 1daad98176 Linux: always check or verify return of igrab() ... zhold() wraps igrab() on Linux, and igrab() may fail when the inode is in the process of being deleted. This means zhold() must only be called when a reference exists and therefore it cannot be deleted. This is the case for all existing consumers so add a VERIFY and a comment explaining this requirement.
