Agreed.

Please explain in the patch description why a holder pointer is
introduced in struct bdev_handle and how it relates to the bd_holder
pointer in struct block_device. Is one of th

Create struct bdev_handle that contains all parameters that need to be
passed to blkdev_put() and provide blkdev_get_handle_* functions that
return this structure instead of plain bdev pointer. This will
eventually allow us to pass one more argument to blkdev_put() without
too much hassle.
