https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D248050 Mark Johnston <markj@FreeBSD.org> changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |markj@FreeBSD.org Status|New |Closed Resolution|--- |Not A Bug --- Comment #2 from Mark Johnston <markj@FreeBSD.org> --- This is by design, though the behaviour is admittedly not intuitive. When = you kldload dtrace, dtrace.ko gets a reference; loading dtraceall.ko adds a sec= ond reference to dtrace.ko. The first attempt to unload dtrace releases the initial reference, but dtraceall.ko's reference ensures that dtrace.ko remains loaded. The second attempt to unload fails because dtraceall.ko still depends on dtrace.ko.=20 Unloading dtraceall.ko should cause dtrace.ko to be unloaded automatically = in that case. --=20 You are receiving this mail because: You are the assignee for the bug.=
