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() block.c | 35 +++++++++++++++++++---------------- block/blkdebug.c | 20 ++------------------ block/commit.c | 12 +----------- block/io.c | 26 ++++++++++++++++++++++++++ block/mirror.c | 12 +----------- block/raw-format.c | 6 ------ include/block/block.h | 1 - include/block/block_int.h | 25 +++++++++++++++++++++++-- 8 files changed, 72 insertions(+), 65 deletions(-) -- 2.11.0
