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.
