This patch series aims to improve the speed of qemu-img rebase.
1. Mainly by removing unnecessary reads when rebasing on the same
chain.
2. But also by minimizing the number of bdrv_open calls rebase
requires.
v2:
* Added missing g_free in
"qemu-img: rebase: Reuse in-chain BlockDriverState"
v3:
* Rebased on top of "Allow rebase with no input base" series
v4 & v5:
* Using backing_bs(bs) when a prefix was detected since bs was
already checked for allocation.
Sam Eiderman (3):
qemu-img: rebase: Reuse parent BlockDriverState
qemu-img: rebase: Reduce reads on in-chain rebase
