[PATCH 1/4] migration/ram: only possible bit set in invalid_flags is RAM_SAVE_FLAG_COMPRESS_PAGE |
Date: |
Sun, 6 Oct 2019 06:05:14 +0800 |
The only possible bit set in invalid_flags is
RAM_SAVE_FLAG_COMPRESS_PAGE at the beginning of function
ram_load_precopy(), which means it is not necessary to do
another check for RAM_SAVE_FLAG_COMPRESS_PAGE bit.
