Mdrecovery in RAID0

[Hardware Stuff]

I noticed that top shows an mdrecoveryd process, it's existance
puzzles me.  Based on skimming the list about recent RAID5 changes, I
had thought that such a process would only exist for reconstruction of
a RAID5 disk set.  While I did initially enable all RAID options, my
recent kernel builds have been exclusively RAID0.  /proc/mdstat
confirms only a RAID0 personality.

What does mdrecoveryd do for a RAID0 system?  Perhaps the name is
misleading?

TIA.
