Subject: [PATCH v7 2/6] dtprobed: stop skipping zero-tracepoint probes in dof_stash.c
Date: Wed, 6 Nov 2024 11:29:38 +0000 [thread overview]
Message-ID: <20241106112942.264351-3-nick.alcock@oracle.com> (raw)
In-Reply-To: <20241106112942.264351-1-nick.alcock@oracle.com>
We already validate that they don't exist in dof_parser.c, so no such probes
can ever get here. Handling this impossible, untestable case has just got
harder, because we'd have to skip DIT_ARGS_{NATIVE,XLAT,MAP} records too.
Just stop considering it.
