[Qemu-devel] [PATCH 0/5] block: Drop drv parameter from bdrv_open()

[Max Reitz <mreitz@redhat.com>]

We don't really need that parameter, so let's drop it. Doing so may even
fix some bugs, see
http://lists.nongnu.org/archive/html/qemu-block/2015-08/msg00171.html.

In the course of writing this series, I had to decide whether the make
sure all callers of bdrv_find_whitelisted_format() would still only
accept whitelisted formats, which you'd think would be a good idea; but
the only caller left was qmp_change_blockdev(), so I guess noone really
cared about it anymore, instead relying on use_bdrv_whitelist alone.

So I decided dropped bdrv_find_whitelisted_format() completely. If you
feel this is a bad decision, feel free to argue but then I guess we'll
have to reevaluate all bdrv_find_format() calls whether they should
actually be bdrv_find_whitelisted_format() calls.


Max Reitz (5):
  block: Always pass NULL as drv for bdrv_open()
  block: Drop drv parameter from bdrv_open()
  block: Drop drv parameter from bdrv_open_inherit()
  block: Drop drv parameter from bdrv_fill_options()
  block: Drop bdrv_find_whitelisted_format()
