		struct ubi_volume *	vol,
		const void __user *	buf,
		int	count
	)

ubi_more_leb_change_data - accept more data for atomic LEB change. : UBI device description object : volume description object : write data (user-space memory buffer) : how much bytes to write

This function accepts more data to the volume which is being under the "atomic LEB change" operation. It may be called arbitrary number of times until all data arrives. This function returns %0 in case of success, number of bytes written during the last call if the whole "atomic LEB change" operation has been successfully finished, and a negative error code in case of failure.

ubi_more_update_data - write more update data. : UBI device description object : volume description object : write data (user-space memory buffer) : how much bytes to write

This function writes more data to the volume which is being updated. It may be called arbitrary number of times until all the update data arriveis. This function returns %0 in case of success, number of bytes written during the last call if the whole volume update has been successfully finished, and a negative error code in case of failure.

		const struct ubi_leb_change_req *	req
	)

ubi_start_leb_change - start atomic LEB change. : UBI device description object : volume description object : operation request

This function starts atomic LEB change operation. Returns zero in case of success and a negative error code in case of failure.

		struct ubi_volume *	vol,
		long long	bytes
	)

ubi_start_update - start volume update. : UBI device description object : volume description object : update bytes

This function starts volume update operation. If is zero, the volume is just wiped out. Returns zero in case of success and a negative error code in case of failure.
