[Qemu-devel] [PATCH v5 0/4] block: Block driver callbacks fixes


From: Manos Pitsidianakis
Subject: [Qemu-devel] [PATCH v5 0/4] block: Block driver callbacks fixes
Date: Thu, 13 Jul 2017 13:01:13 +0300

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

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()
