[Qemu-devel] [PATCH 0/2] COW: Speed up writes

2013-11-15 Thread Charlie Shepherd 
v4:
  - Rebase onto master
  - Fix compilation error

v3:
  - Refix cow_update_bitmap and squash patches 1 & 3 together to ensuring that 
we only flush if
necessary, patch 1 on its own would change this causing a regression.
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.

  COW: Speed up writes
  COW: Extend checking allocated bits to beyond one sector
