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 commit ced1484322 of
https://github.com/XanClic/qemu.git block branch
v6:
fix parameter order in bdrv_truncate() return call in
block: pass bdrv_* methods to bs->file by default in block filters
v5:
rebase against ced1484322 of https://github.com/XanClic/qemu.git block to fix
apply conflicts
add suggested commit message in block: remove unused bdrv_media_changed
add is_filter implication in commit message of block: remove bdrv_truncate
callback in blkdebug
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 unused bdrv_media_changed
block: remove bdrv_truncate callback in blkdebug
block: add default implementations for bdrv_co_get_block_status()
