[Qemu-block] [PATCH for-2.4 0/5] block: Fix backing file child when modi


From: Kevin Wolf
Subject: [Qemu-block] [PATCH for-2.4 0/5] block: Fix backing file child when modifying graph
Date: Wed, 8 Jul 2015 21:36:38 +0200

This series is extracted from my work towards removing bdrv_swap(),
which is targeted for 2.5. It contains a fix for dangling pointers when
modifying the BDS graph and its dependencies.

I didn't bother to split patches of which only a part is required, nor
did I remove references to the future bdrv_swap removal (after all, it
will happen, even if the patches will be delayed by the 2.4 freeze).

Specifically, bdrv_open/unref_child() are yet unused in this series; the
respective patches are included because of bdrv_attach/detach_child().

Kevin Wolf (5):
  block: Move bdrv_attach_child() calls up the call chain
  block: Introduce bdrv_open_child()
  block: Introduce bdrv_unref_child()
  block: Reorder cleanups in bdrv_close()
  block: Fix backing file child when modifying graph
