Recovery on incomplete write

Hi all,

I have wondered that md.c handles incomplete block(page)s
correctly.
Am I mistaken ?

1) _mdnblocks() takes the last incomplete block into account

2) mdextend() doesn't care about the existence of incomplete   block(page)s.

3) In spite of 1)2),mdextend() does nothing when incomplete   write occurs.

Comments ?

If I am right,I would provide a patch.

Regards.
