when i use 'mdadm -S /dev/md127', it produce kernel event with no stop

when I plug a disk which has superblock(it used to be a part of a raid5) into computer.

at the same time, I use 'udevadm monitor' to monitor the kernel event.

i use 'cat /proc/mdstat',it show me as below:

Personalities :
md127 : inactive sdc[8](S

976761560 blocks super 1.2

unused devices: <none>

so i use 'mdadm -S /dev/md127' to stop it, this show me that :

mdadm: stopped /dev/md127

but the 'udevadm monitor'begin to show me that without stop!

i copy some messages:

What does

cat /proc/mdstat

show you?

Does that report that the device is stopped?
