NeilBrown a5c308d4d1 md/raid5: suspend shouldn't affect read requests.
md allows write to regions on an array to be suspended temporarily.
This allows user-space to participate is aspects of reshape.
In particular, data can be copied with not risk of a race.
We should not be blocking read requests though, so don't.
