[PATCH v4 6/6] net/colo-compare.c: Correct ordering in complete and finalize |
Date: |
Mon, 4 May 2020 12:28:22 +0200 |
In colo_compare_complete, insert CompareState into net_compares
only after everything has been initialized.
In colo_compare_finalize, remove CompareState from net_compares
before anything is deinitialized.
