[PATCH] md/bitmap: remove dead code from md/bitmap

 *

 * flush after percent set rather than just time based. (maybe both).

 * wait if count gets too high, wake when it drops to half.

 * allow bitmap to be mirrored with superblock (before or after...)

 * allow hot-add to re-instate a current device.

 * allow hot-add of bitmap after quiessing device
