You are likely correct as the [ext4lazyinput] process is now gone. 
Probably finished up last night as the drives are quiet now.

For completeness:

> What did "cat /proc/mdstat" say?

# cat /proc/mdstat 
Personalities : [raid1] 
md0 : active raid1 sdc1[1] sdb1[0]
      3906885440 blocks super 1.2 [2/2] [UU]
      bitmap: 0/30 pages [0KB], 65536KB chunk

unused devices: <none>

Unfortunely, I can not be 100% certain if the [ext4lazyinput] process
was still active when I captured the mdstat output shown above.  But
that is what it says now that the process is gone.

Thanks to everyone for their input.
