The branch releng/15.1 has been updated by cperciva: URL: https://cgit.FreeBSD.org/src/commit/?id=c4be32aabf91ec74d95296a3455bb7ed05b50ff5 commit c4be32aabf91ec74d95296a3455bb7ed05b50ff5 Author: Aaron LI <aly@aaronly.me> AuthorDate: 2026-03-17 04:53:49 +0000 Commit: Colin Percival <cperciva@FreeBSD.org> CommitDate: 2026-05-06 16:30:14 +0000 tail(1): Fix -r (reverse) to work on pseudo filesystems Pseudo filesystems (e.g., procfs) advertise a zero file size. Fix reverse() to handle such a case similarly as forward() so that '-r' works on pseudo filesystems.
