In your example above, if your /dev/sdc is not part of an array, kernel will not
remove it. If it happens this is a bug.
If /dev/sda and /dev/sdb are part of an array, they will be removed, and this is
*not* a bug, why it should be..?

Yes I agree, this could be an interesting feature, but imho is not relevant with
this issue.

Workaround (patch) that I added in the latest revision isn't elegant, but imho
it fixed that issue. If it doesn't, please reopen this bug and write a testcase.
