John Garry 8b3ce085b5 block: avoid possible overflow for chunk_sectors check in blk_stack_limits() ... [ Upstream commit 448dfecc7f ] In blk_stack_limits(), we check that the t->chunk_sectors value is a multiple of the t->physical_block_size value. However, by finding the chunk_sectors value in bytes, we may overflow the unsigned int which holds chunk_sectors, so change the check to be based on sectors.
