set_capacity() sets device capacity by the number of 512 bytes sectors. null_blk calculates the number of sectors by size / bs and calls set_capacity. This leads to the wrong number of sectors when bs is not 512 bytes. Signed-off-by: Matias Bjørling <m@bjorling.me> --- drivers/block/null_blk.c | 3 +-- 1 file changed, 1 insertion(+), 2 deletions(-)
