[PATCH v4 0/6] migration: auto-converge refinements for huge VM

[yong.huang@smartx.com]

From: Hyman Huang <yong.huang@smartx.com>

v4:
1. split the [PATCH v3 1/6] into smaller patches.
2. refine some comment and commit message
3. fix race issue for the throttle_dirty_sync_timer
4. refine the util function cpu_throttle_dirty_sync_timer

Thanks Peter for the suggestions.

Please review.

v3:
1. drop the responsive throttle patchset
2. rename background sync to periodic ramblock dirty sync
3. move the cpu-throttle.* from system to migration
4. remove "rs" parameter in migration_bitmap_sync_precopy
5. implement periodic ramblock dirty sync in cpu-throttle.c
6. move the test change into a separate patch

To simplify the cover letter, i have dropped the test data,
please refer to

for more test details.

Thanks Peter and Fabiano for the suggestions and comments.

Please review.
