Network block device layer.

Typedef Documentation

typedef void(* spdk_nbd_start_cb) (void *cb_arg, struct spdk_nbd_disk *nbd, int rc)

Called when an NBD device has been started.

On success, rc is assigned 0; On failure, rc is assigned negated errno.

void spdk_nbd_fini	(	spdk_nbd_fini_cb	cb_fn,
		void *	cb_arg )

Stop and close all the running network block devices.

Parameters

cb_fn	Callback to be always called.
cb_arg	Passed to cb_fn.

int spdk_nbd_init ( void )

Initialize the network block device layer.

Start a network block device backed by the bdev.

Parameters

bdev_name	Name of bdev exposed as a network block device.
nbd_path	Path to the registered network block device.
cb_fn	Callback to be always called.
cb_arg	Passed to cb_fn.

int spdk_nbd_stop ( struct spdk_nbd_disk * nbd )

Stop the running network block device safely.

Parameters

nbd	A pointer to the network block device to stop.

void spdk_nbd_write_config_json ( struct spdk_json_write_ctx * w )

Write NBD subsystem configuration into provided JSON context.

Parameters

w	JSON write context
