When the discard length is not a multiple of RSXX_HW_BLK_SIZE, the discard code will get into an infinite loop, even discarding data it is not supposed to. This will also hang the system. This can be reproduced by doing an ioctl BLKDISCARD to /dev/rsxx0 with range from 0 to 1024.
That is a bug that should be fixed in the discard code, not worked around in the driver.
