[Qemu-devel] [PATCH v3 0/3] qemu-img: rebase: Improve/optimize rebase operation

Posted by Sam Eiderman 4 years, 11 months ago

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

Sam Eiderman (3):
  qemu-img: rebase: Reuse parent BlockDriverState
  qemu-img: rebase: Reduce reads on in-chain rebase
  qemu-img: rebase: Reuse in-chain BlockDriverState
