The branch stable/15 has been updated by des: URL: https://cgit.FreeBSD.org/src/commit/?id=76fd9309e55e93c0c998db16c26ab480e49887a2 commit 76fd9309e55e93c0c998db16c26ab480e49887a2 Author: Dag-Erling Smørgrav <des@FreeBSD.org> AuthorDate: 2025-09-23 12:56:04 +0000 Commit: Dag-Erling Smørgrav <des@FreeBSD.org> CommitDate: 2025-10-02 08:19:23 +0000 pwait: Fix timeout unit parser The timeout parser would check the first character after the number and ignore any subsequent ones.
