- * num_devs is the number of devices the caller is going to scan.
- * When 0 the caller doesn't know, and we use the default cache size.
- * When non-zero, allocate at least num_devs bcache blocks.
- * num_devs doesn't really tell us how many bcache blocks we'll use
- * because it includes lvm devs and non-lvm devs, and each lvm dev
- * will often use a number of bcache blocks.
- *
  * We don't know ahead of time if we will find some VG metadata 
  * that is larger than the total size of the bcache, which would
  * prevent us from reading/writing the VG since we do not dynamically
