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. Fix incorrect condition in out-of-image check. v11: 1: Use bdrv_nb_sectors() instead of bdrv_getlength() to get image size in sectors. 7,9: Add coroutine_fn and GRAPH_RDLOCK annotations. v10: 8: Add a comment. 9: Exclude unrelated changes. v9: 3: Add (high_off == 0) case handling. 7: Move res->image_end_offset setting to parallels_check_outside_image(). 8: Add a patch with a statistics calculation fix. 9: Remove redundant high_off calculation. 12: Change the condition to (off + s->cluster_size > size). v8: Rebase on the top of the current master branch. v7: 1,2: Fix string lengths in the commit messages. 3: Fix a typo in the commit message. v6: 1: Move the error check inside the loop. Move file size getting to the function beginning. Skip out-of-image offsets. 2: A new patch - don't let high_off be more than the end of the last cluster. 3: Set data_end without any condition. 7: Move data_end setting to parallels_check_outside_image(). 8: Remove s->data_end setting from parallels_check_leak(). Fix 'i' type. v5: 2: Change the way of data_end fixing. 6,7: Move data_end check to parallels_check_leak(). v4: 1: Move s->data_end fix to parallels_co_check(). Split the check in parallels_open() and the fix in parallels_co_check() to two patches. 2: A new patch - a part of the patch 1. Add a fix for data_end to parallels_co_check(). 3: Move offset convertation to parallels_set_bat_entry(). 4: Fix 'ret' rewriting by bdrv_co_flush() results. 7: Keep 'i' as uint32_t. v3: 1-8: Fix commit message. v2: 2: A new patch - a part of the splitted patch 2. 3: Patch order was changed so the replacement is done in parallels_co_check. Now we use a helper to set BAT entry and mark the block dirty. 4: Revert the condition with s->header_unclean. 5: Move unrelated helper parallels_set_bat_entry creation to a separate patch. 7: Move fragmentation counting code to this function too. 8: Fix an incorrect usage of WITH_QEMU_LOCK_GUARD.
