The branch releng/14.0 has been updated by asomers: URL: https://cgit.FreeBSD.org/src/commit/?id=bc417deae52aa6a75003687d4f78cff89a3e569e commit bc417deae52aa6a75003687d4f78cff89a3e569e Author: Alan Somers <asomers@FreeBSD.org> AuthorDate: 2023-10-06 19:46:42 +0000 Commit: Alan Somers <asomers@FreeBSD.org> CommitDate: 2023-10-21 21:40:11 +0000 Fix intermittency in the sys.fs.fusefs.mknod.main test In the Mknod.parent_inode test case, the kernel sends an extra FUSE_FORGET message. But because it gets sent asynchronously with the failing syscall, it doesn't always get received before the test ends. So we never setup an expectation for it. And 90+% of the time the test would exit successfully. Fix the intermittency by always waiting to receive the FUSE_FORGET message. Sponsored by: Axcient (cherry picked from commit 86885b18689889e9b9142fd31d8c67f21334ba32) Fix intermittency in the sys.fs.fusefs.symlink.main test This change is identical to 86885b18689 but for symlink instead of mknod. The kernel sends a FUSE_FORGET asynchronously with the final syscall. The lack of an expectation caused this test to occasionally fail. Also, remove a sleep that accidentally snuck into a different test.
