From dcbf37ce41a52698550f8f8b2f14b5e6fee22d2d Mon Sep 17 00:00:00 2001 From: Kevin Wolf Date: Thu, 9 Mar 2017 11:49:16 +0100 Subject: commit: Implement .bdrv_refresh_filename We want query-block to return the right filename, even if a commit job put a bdrv_commit_top on top of the actual image format driver. Let bdrv_commit_top.bdrv_refresh_filename get the filename from its backing file.
