The branch stable/13 has been updated by mhorne: URL: https://cgit.FreeBSD.org/src/commit/?id=fc7febf483a4910b024b34ab8620e6ac14590c08 commit fc7febf483a4910b024b34ab8620e6ac14590c08 Author: Mitchell Horne <mhorne@FreeBSD.org> AuthorDate: 2021-09-29 17:44:27 +0000 Commit: Mitchell Horne <mhorne@FreeBSD.org> CommitDate: 2021-10-15 15:20:48 +0000 minidump: De-duplicate the progress bar The implementation of the progress bar is simple, but duplicated for most minidump implementations. Extract the common bits to kern_dump.c. Ensure that the bar is reset with each subsequent dump; this was only done on some platforms previously.
