The branch stable/15 has been updated by asomers: URL: https://cgit.FreeBSD.org/src/commit/?id=b6533f67c3990dd7db5b37625730db83bf2adc18 commit b6533f67c3990dd7db5b37625730db83bf2adc18 Author: Alan Somers <asomers@FreeBSD.org> AuthorDate: 2025-12-21 15:32:31 +0000 Commit: Alan Somers <asomers@FreeBSD.org> CommitDate: 2026-01-20 22:31:30 +0000 fusefs: Fix further intermittency in the BadServer.ShortWrite test case After being unmounted, the mockfs server would occasionally read from /dev/fuse again, if the main function didn't exit fast enough, getting an ENODEV error. Handle that appropriately.
