[PATCH 0/9] parallels: Refactor the code of images checks and fix a bug

[Alexander Ivanov]

Fix image inflation when offset in BAT is out of image.

Replace whole BAT syncing by flushing only dirty blocks.

Move all the checks outside the main check function in
separate functions

Use WITH_QEMU_LOCK_GUARD for simplier code.

v4 changes:

  Move s->data_end fixing to parallels_co_check(). Split the check
  in parallels_open() and the fix in parallels_co_check() to two patches.

  Move offset convertation to parallels_set_bat_entry().

  Fix 'ret' rewriting by bdrv_co_flush() results.

  Keep 'i' as uint32_t.
