Any insight on where to put the log of the mirror target when mapping over a
MD-created raid1 ?

MD effectively uses a log with a single region in it.  So we only need
3 sectors (2 for the header 1 for the bitset) for the log, is there
any space in the MD metadata where this could be placed ?

The MD device size is 64K aligned and MD superblock size is 4K.  In term
of sectors, the calculation is as follows:

Oops.  I was thinking raid1 when saying : "The MD device size is 64K
aligned."  I should have said : "The new MD child size is 64K aligned."
