The branch main has been updated by glebius: URL: https://cgit.FreeBSD.org/src/commit/?id=175d4d69887fb103f0b0385cbbafec0432284ff3 commit 175d4d69887fb103f0b0385cbbafec0432284ff3 Author: Gleb Smirnoff <glebius@FreeBSD.org> AuthorDate: 2023-12-19 18:21:56 +0000 Commit: Gleb Smirnoff <glebius@FreeBSD.org> CommitDate: 2023-12-19 18:21:56 +0000 tcp_hpts: use tcp_pace.cts_last_ran for last ran table Remove the global cts_last_ran and use already existing unused field of struct tcp_hptsi, which seems originally planned to hold this table. This makes it consistent with other malloc-ed tables, like main array of HPTS entities and CPU groups.
