Function Documentation

struct fcoe_ctlr_device* fcoe_ctlr_device_add ( struct device *  parent, struct fcoe_sysfs_function_template *  f, int  priv_size  )

read

fcoe_ctlr_device_add() - Add a FIP ctlr to sysfs : The parent device to which the fcoe_ctlr instance should be attached : The LLD's FCoE sysfs function template pointer : Size to be allocated with the fcoe_ctlr_device for the LLD

This routine allocates a FIP ctlr object with some additional memory for the LLD. The FIP ctlr is initialized, added to sysfs and then attributes are added to it.

void fcoe_ctlr_device_delete

(

struct fcoe_ctlr_device *

ctlr

)

fcoe_ctlr_device_delete() - Delete a FIP ctlr and its subtree from sysfs : A pointer to the ctlr to be deleted

Deletes a FIP ctlr and any fcfs attached to it. Deleting fcfs will cause their childen to be deleted as well.

The ctlr is detached from sysfs and it's resources are freed (work q), but the memory is not freed until its last reference is released.

This routine expects no locks to be held before calling.

TODO: Currently there are no callbacks to clean up LLD data for a fcoe_fcf_device. LLDs must keep this in mind as they need to clean up each of their LLD data for all fcoe_fcf_device before calling fcoe_ctlr_device_delete.

struct fcoe_fcf_device* fcoe_fcf_device_add ( struct fcoe_ctlr_device *  ctlr, struct fcoe_fcf_device *  new_fcf  )

read

fcoe_fcf_device_add() - Add a FCoE sysfs fcoe_fcf_device to the system : The fcoe_ctlr_device that will be the fcoe_fcf_device parent : A temporary FCF used for lookups on the current list of fcfs

Expects to be called with the ctlr->lock held

fcoe_fcf_device_delete() - Delete a FIP fcf : Pointer to the fcf which is to be deleted

Queues the FIP fcf on the devloss workqueue

Expects the ctlr_attrs mutex to be held for fcf state change.
