Subject: block: Simplify bdrv_reopen_abort()
X-Git-Tag: v3.1.0~208^2~3
X-Git-Url: https://git.proxmox.com/?a=commitdiff_plain;h=1bab38e7bd29347aca642c55a1de91ec6680efce;p=mirror_qemu.git

block: Simplify bdrv_reopen_abort()

If a bdrv_reopen_multiple() call fails, then the explicit_options
QDict has to be deleted for every entry in the reopen queue. This must
happen regardless of whether that entry's bdrv_reopen_prepare() call
succeeded or not.

This patch simplifies the cleanup code a bit.
