The branch stable/13 has been updated by cperciva: URL: https://cgit.FreeBSD.org/src/commit/?id=a04376045ddbcb44d46163b8f4418a587162c122 commit a04376045ddbcb44d46163b8f4418a587162c122 Author: Colin Percival <cperciva@FreeBSD.org> AuthorDate: 2021-12-30 19:47:50 +0000 Commit: Colin Percival <cperciva@FreeBSD.org> CommitDate: 2022-01-16 05:33:48 +0000 Fix variable name: freq_khz -> freq An earlier version of this code computed the TSC frequency in kHz. When the code was changed to compute the frequency more accurately, the variable name was not updated.
