[Devel] [PATCH hci-8.1 v7 2/8] block/blk-cbt: shift the block size as unsigned

[no-reply at sashiko.virtuozzo.com]

> cbt_ioc_init() accepts any power of two block size, so block_bits can be
> 31, and then 1 << block_bits overflows int. In blk_cbt_add() and
> cbt_ioc_set() the sign extended block size then makes the rounded up
> block counts wrong. Shift an unsigned one explicitly everywhere the
> block size is computed.
