ATA_FINALIZE_PORT_OP(9)               libata Core Internals               ATA_FINALIZE_PORT_OP(9)



NAME
       ata_finalize_port_ops - finalize ata_port_operations

SYNOPSIS
       void ata_finalize_port_ops(struct ata_port_operations * ops);

ARGUMENTS
       ops
           ata_port_operations to finalize

DESCRIPTION
       An ata_port_operations can inherit from another ops and that ops can again inherit from
       another. This can go on as many times as necessary as long as there is no loop in the
       inheritance chain.

       Ops tables are finalized when the host is started. NULL or unspecified entries are
       inherited from the closet ancestor which has the method and the entry is populated with
       it. After finalization, the ops table directly points to all the methods and ->inherits is
       no longer necessary and cleared.

       Using ATA_OP_NULL, inheriting ops can force a method to NULL.

       LOCKING: None.
