From 765003db029ed4660a09807958276e251de84fac Mon Sep 17 00:00:00 2001 From: Kevin Wolf Date: Mon, 3 Feb 2014 14:49:42 +0100 Subject: block: Fail gracefully with missing filename This fixes a regression introduced in commit 2a05cbe42 ('block: Allow block devices without files'): $ qemu-system-x86_64 -drive driver=file qemu-system-x86_64: block.c:892: bdrv_open_common: Assertion `!drv->bdrv_needs_filename || filename != ((void *)0)' failed. Now the respective check must be performed not only in bdrv_file_open(), but also in bdrv_open().
