[Qemu-devel] [PATCH 00/11] block: Use BB function in .bdrv_create() implementations

[Kevin Wolf]

All users of the block layers are supposed to go through a BlockBackend.
The .bdrv_create() implementations are such users, so this series
converts them.

This series (specifically patch 1) will also help with moving the
writethrough cache implementation from BDS to BB, where it really
belongs. Once this is moved, it wouldn't be possible to use bdrv_open()
to use a standalone BDS writethrough any more.

Of course, writethrough doesn't make any sense in .bdrv_create() anyway,
so while I'm still converting everything to BB where it would keep
working (because that's the Right Thing), the drivers don't actually
make use of this fact any more after this series.
