[Qemu-devel] [PATCH 12/20] mirror: support arbitrarily-sized iterations

2012-12-12 Thread Paolo Bonzini
Yet another optimization is to extend the mirroring iteration to include more adjacent dirty blocks. This limits the number of I/O operations and makes mirroring efficient even with a small granularity. Most of the infrastructure is already in place; we only need to put a loop around the computat
