https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D266098 Mark Johnston <markj@FreeBSD.org> changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |markj@FreeBSD.org Assignee|bugs@FreeBSD.org |markj@FreeBSD.org --- Comment #1 from Mark Johnston <markj@FreeBSD.org> --- It's because there is a io:::start probe in devstat_start_transaction(), but there is no BIO to reference. I'll commit a patch to remove those probes, since I don't think they're very useful. BTW, this script isn't going to give you much information on FreeBSD. The = io probes are too "deep" in the I/O path to retain any association with the process that initiated the I/O. That is, "execname" will not tell you much= .=20 In some cases it might, but that depends on the filesystem and GEOM provide= rs in use. --=20 You are receiving this mail because: You are the assignee for the bug.=
