[Qemu-devel] [PATCH v3 for-2.10 0/4] block: Add errp to b{lk, drv}_truncate()

[Max Reitz]

Having an Error parameter for these functions makes sense because we
sometimes want a bit more information than just "Something failed". Some
drivers already use error_report() and the like to emit this additional
information, so it's rather obvious that we do want a real error object
here.


v3:
- Patch 2: Keep "Could not resize image" message in qcow2_create2() by
           using error_prepend() [Kevin]
- Patch 3: Dropped archipelago
- Patch 4:
  - Keep errno information where available [Kevin]
  - Make all drivers generate error messages [Stefan/Eric]
  - Drop generic error message from bdrv_truncate() [Stefan/Eric]


Max Reitz (4):
  block/vhdx: Make vhdx_create() always set errp
  block: Add errp to b{lk,drv}_truncate()
  block: Add errp to BD.bdrv_truncate()
  block: Add .bdrv_truncate() error messages
