Throttle device parsing problem

[leonidgurevich]

Hi,
Here is the problem:
For blkio_config we receive parsing error when using string for rate like in following:
device_write_bps:

• path: /dev/sdb
  rate: '1024k'

Error message states that only integer is expected, while spec states that for device_write_bps and device_read_bps both an integer or a string is allowed - see below:

device_read_bps, device_write_bps
Set a limit in bytes per second for read / write operations on a given device. Each item in the list must have two keys:

• path, defining the symbolic path to the affected device
• rate, either as an integer value representing the number of bytes or as a string expressing a byte value
