[Qemu-devel] [PATCH v4 0/4] block: Block driver callbacks fixes |

This series makes implementing some of the bdrv_* callbacks easier for block
filters 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
da4bd74d2450ab72a7c26bbabb10c6a287dd043e
v4:
forward only for block filters
new patch: remove bdrv_media_changed
dropped commit `block: Use defaults of bdrv_* callbacks in raw`, since raw is
not a filter driver and is incompatible with the changes.
v3:
minor changes by Eric Blake's suggestion
new patch: remove bdrv_truncate method from blkdebug
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 (4):
block: pass bdrv_* methods to bs->file by default in block filters
block: remove bdrv_media_changed
block: remove bdrv_truncate callback in blkdebug
block: add default implementations for bdrv_co_get_block_status()
