[PATCH v2 0/5] block: Generic file creation fallback |

Hi,
As version 1, this series adds a fallback path for creating files (on
the protocol layer) if the protocol driver does not support file
creation, but the file already exists.
Branch: https://github.com/XanClic/qemu.git skip-proto-create-v2
Branch: https://git.xanclic.moe/XanClic/qemu.git skip-proto-create-v2
v2:
- Drop blk_truncate_for_formatting(): It doesn’t make sense to introduce
this function any more after 26536c7fc25917d1bd13781f81fe3ab039643bff
(“block: Do not truncate file node when formatting”), because we’d
only use it in bdrv_create_file_fallback().
Thus, it makes more sense to create special helper functions
specifically for bdrv_create_file_fallback().
- Thus, dropped patches 2 and 3.
- And changed patch 4 to include those helper functions.
- Rebased, which was a bit of a pain.
git-backport-diff against v1:
Key:
[----] : patches are identical
[####] : number of functional differences between upstream/downstream patch
[down] : patch is downstream-only
The flags [FC] indicate (F)unctional and (C)ontextual differences, respectively
