[Qemu-devel] [PATCH v2 0/3] COW: Speed up writes

[Charlie Shepherd]

v2:
  - Fix bit position calculations in cow_update_bitmap
  - Add necessary check in cow_set_bits

Following on from Paolo's commits 26ae980 and 276cbc7, this patchset
implements some changes he recommended earlier which I didn't previously have
time to do while on GSoC.

Charlie Shepherd (3):
  COW: Speed up writes
  COW: Extend checking allocated bits to beyond one sector
  COW: Skip setting already set bits
