Parallels format driver: * make some preparation * add dirty bitmap saving * make dirty bitmap RW * fix broken checks * refactor leak check * add parallels format support to several tests
You could find these patches in my repo: https://github.com/AlexanderIvanov-Virtuozzo/qemu/tree/parallels-v2 v2: 1: New patch to fix double free error. 4: Fixed clusters leaks. 15: Fixed (end_off != s->used_bmap_size) handling in parallels_truncate_unused_clusters(). 16,17: Changed the sequence of the patches - in this way we have correct leaks check. Alexander Ivanov (20): parallels: Set s->used_bmap to NULL in parallels_free_used_bitmap() parallels: Move inactivation code to a separate function parallels: Add mark_unused() helper parallels: Move host clusters allocation to a separate function parallels: Set data_end value in parallels_check_leak() parallels: Recreate used bitmap in parallels_check_leak() parallels: Add a note about used bitmap in parallels_check_duplicate() parallels: Create used bitmap even if checks needed parallels: Make mark_used() and mark_unused() global functions parallels: Add dirty bitmaps saving parallels: Let image extensions work in RW mode parallels: Handle L1 entries equal to one parallels: Make a loaded dirty bitmap persistent parallels: Reverse a conditional in parallels_check_leak() to reduce indents parallels: Truncate images on the last used cluster parallels: Check unused clusters in parallels_check_leak() parallels: Remove unnecessary data_end field tests: Add parallels images support to test 165 tests: Turned on 256, 299, 304 and block-status-cache for parallels format tests: Add parallels format support to image-fleecing block/parallels-ext.c | 182 +++++++++- block/parallels.c | 361 ++++++++++++-------- block/parallels.h | 15 +- tests/qemu-iotests/165 | 40 ++- tests/qemu-iotests/256 | 2 +- tests/qemu-iotests/299 | 2 +- tests/qemu-iotests/304 | 2 +- tests/qemu-iotests/tests/block-status-cache | 2 +- tests/qemu-iotests/tests/image-fleecing | 13 +- 9 files changed, 447 insertions(+), 172 deletions(-) -- 2.34.1
