void memstick_detect_change ( struct memstick_host * host )

memstick_detect_change - schedule media detection on memstick host - host to use

void memstick_free_host ( struct memstick_host * host )

memstick_free_host - free memstick host - host to use

void memstick_init_req	(	struct memstick_request *	mrq,

		const void *	buf,
		size_t	length
	)

memstick_init_req - set request fields needed for short data transfer - request to use - memstick Transport Protocol Command - TPC argument buffer - TPC argument size

The intended use of this function (transfer of data items several bytes in size) allows us to just copy the value between request structure and user supplied buffer.

void memstick_init_req_sg	(	struct memstick_request *	mrq,

memstick_init_req_sg - set request fields needed for bulk data transfer - request to use - memstick Transport Protocol Command - TPC argument

Definition at line 268 of file memstick.c.

void memstick_new_req ( struct memstick_host * host )

memstick_new_req - notify the host that some requests are pending - host to use

Definition at line 252 of file memstick.c.

int memstick_next_req	(	struct memstick_host *	host,
		struct memstick_request **	mrq
	)

memstick_next_req - called by host driver to obtain next request to process - host to use - pointer to stick the request to

Host calls this function from idle state (*mrq == NULL) or after finishing previous request (*mrq should point to it). If previous request was unsuccessful, it is retried for predetermined number of times. Return value of 0 means that new request was assigned to the host.
