Description

- https://github.com/ceph/ceph/pull/29537

dout(20) << __func__ << " id " << id
         << " alloc_size 0x" << std::hex << alloc_size[id]
         << " size 0x" << bdev[id]->get_size() << std::dec << dendl;

- This will help to verify what value the BlueStore OSD is using for bluefs alloc_size.
