Subject: Re: [DTrace-devel] [PATCH] pid: USDT probes cannot have "-" as function name
Date: Mon, 9 Feb 2026 14:22:11 -0500 [thread overview]
Message-ID: <a1051394-2811-d0e7-ecc4-f421396b2bf4@oracle.com> (raw)
In-Reply-To: <DS0PR10MB7522231ADA11F5C6C606FC8EC265A@DS0PR10MB7522.namprd10.prod.outlook.com>
Could we have a little more explanation here? Like, what is wrong with
the current behavior (which is... to complain that the probe is not
found?)? And should any test check the behavior?
