[Qemu-block] [PATCH v2 0/5] block: Introduce qemu-img bench |

After merging Den's qcow2 patch to avoid duplicated flushes, I thought I would
be nice to reproduce the problem and I remembered 'qemu-img bench', which I had
posted before as part of more than one RFC series, but which never made it to
master somehow. So here is a rebased and cleaned up version of it, just by
itself, so that it hopefully can be merged finally.
Of course, I failed to actually reproduce the problem on my laptop. Who knows,
something on my system might be more intelligent about useless flushes, or
maybe I just misunderstood what the problematic scenario looks like at the
block level. Doesn't make the tool less useful, though, and I already did the
rebasing.
v2:
- Added --pattern=... option for writes [Den]
- Added --no-drain option for write+flush tests [Den]
Kevin Wolf (5):
qemu-img bench
qemu-img bench: Sequential writes
qemu-img bench: Make start offset configurable
qemu-img bench: Implement -S (step size)
qemu-img bench: Add --flush-interval
