[Qemu-block] [PATCH v2 0/3] block: block driver callbacks fixes

[Manos Pitsidianakis]

This series makes implementing some of the bdrv_* callbacks easier for block
drivers by passing requests to bs->file if bs->drv doesn't implement it instead
of failing, and adding default bdrv_co_get_block_status() implementations.

This is based against Kevin Wolf's block branch, commit
0dd2ec6bc46bd93ea0b9df602962883417f31400

v2:
  do not pass to bs->file if bs->drv is NULL
  move bs->file check outside of bdrv_inc_in_flight() area in bdrv_co_ioctl()
  new patch: remove duplicate code from block/raw-format.c

Manos Pitsidianakis (3):
  block: pass bdrv_* methods to bs->file by default
  block: use defaults of bdrv_* callbacks in raw
  block: add default implementations for bdrv_co_get_block_status()
