[BUG?] count of "Spare Devices" wrong after fail/remove/add

Hi!

While experimenting with fail/remove/add of mdadm

# mdadm --detail /dev/md0
/dev/md0:
        Version : 00.90.00
  Creation Time : Mon Jan 20 22:53:28 2003
     Raid Level : raid1
     Array Size : 40209024 (38.35 GiB 41.22 GB)
    Device Size : 40209024 (38.35 GiB 41.22 GB)
   Raid Devices : 2
  Total Devices : 2
Preferred Minor : 0
    Persistence : Superblock is persistent

    Update Time : Tue Jan 21 00:49:47 2003
          State : dirty, no-errors
 Active Devices : 2
Working Devices : 2
 Failed Devices : 0
  Spare Devices : 2


    Number   Major   Minor   RaidDevice State
       0       3        1        0      active sync   /dev/hda1
       1      22        1        1      active sync   /dev/hdc1
           UUID : d876333b:694e852b:e9a6f40f:0beb90f9

I do wounder why I've got 2 spare drives despite the fact that I
did not add any. I've just got two drives in this raid1 that's it.

Kernel is 2.4.19.
mdadm is 1.0.1

I tried to reproduce this by recreating the array and running
fail/remove/add on it but did not succeed. No reboot.


PS: Array Size : 40209024 (38.35 GiB 41.22 GB)
should IMHO be
    Array Size : 40209024 (38.35 GiB 40.21 GB)
