[PATCH v4 00/21] parallels: Add full dirty bitmap support |
Date: |
Thu, 28 Dec 2023 11:12:11 +0100 |
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-v4
v4:
4: A new patch with limitation of search in parallels_mark_used.
5: Previously 4. Search is limited to (cluster_index + count).
6: Previously 5. Added GRAPH_RDLOCK annotation, added a note in the commit
message.
11: Previously 10. Added GRAPH_RDLOCK annotation.
16-18: Added GRAPH_RDLOCK annotations.
v3:
1: Fixed the order of g_free() and s->used_bmap = NULL.
3,4: Made mark_used() a global function before mark_unused() addition. In
this way we can avoid compilation warnings.
5-9: Patches shifted.
11: Added GRAPH_RDLOCK annotation to parallels_inactivate(). Guard
parallels_close() with GRAPH_RDLOCK_GUARD_MAINLOOP().
12-21: Patches shifted.
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 (21):
parallels: Set s->used_bmap to NULL in parallels_free_used_bitmap()
parallels: Move inactivation code to a separate function
parallels: Make mark_used() a global function
parallels: Limit search in parallels_mark_used to the last marked
claster
parallels: Add parallels_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: 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
