Changes since 2.4.23-pre7-dm1
-----------------------------

Revision 17:
  Correct calculation of the dirty logs bitset size.

Revision 18:
  Correct the sector calculation in map_buffer().

Revision 19:
  If a kcopyd client hadn't allocated enough pages and then submitted a
  large io that was being split into sub jobs we could stall waiting for
  pages.  There is now a kcopyd_client->max_split field that is an
  appropriate number of sub_jobs to split the io into based on the
  number of allocated pages.

Revision 20:
  Fix bug in dm-io.c block size calculation.  [Alasdair Kergon]
