BDEV_STACK_LIMITS(9)                      Block Devices                      BDEV_STACK_LIMITS(9)



NAME
       bdev_stack_limits - adjust queue limits for stacked drivers

SYNOPSIS
       int bdev_stack_limits(struct queue_limits * t, struct block_device * bdev,
                             sector_t start);

ARGUMENTS
       t
           the stacking driver limits (top device)

       bdev
           the component block_device (bottom)

       start
           first data sector within component device

DESCRIPTION
       Merges queue limits for a top device and a block_device. Returns 0 if alignment didn't
       change. Returns -1 if adding the bottom device caused misalignment.
