https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D253500 --- Comment #2 from Alan Somers <asomers@FreeBSD.org> --- Kib's right. The VOP_ADVLOCK interface isn't exactly the same as fcntl. I= t's not legal for op to be F_SETLKW. Instead, it should be F_SETLK and the fla= gs field should contain F_WAIT. You can fix this in fuse_vnop_advlock . The second problem is also likely caused by fuse_vnop_advlock, but I don't have time to debug it right now. If you're planning to submit a fix, could you please also fix and/or extend= the tests in tests/sys/fs/fusefs/locks.cc ? --=20 You are receiving this mail because: You are the assignee for the bug.=
