Subject: [PULL 03/12] dump: Assert cpu_get_note_size() can't fail
Date: Thu, 23 Feb 2023 14:46:17 +0100	[thread overview]
Message-ID: <20230223134626.2107382-4-armbru@redhat.com> (raw)
In-Reply-To: <20230223134626.2107382-1-armbru@redhat.com>

The only way cpu_get_note_size() can return a negative value is
integer overflow in the non-stub versions, which is a programming
error.  The stub version is not actually reachable, because the
cpu_get_dump_info() stub will fail first.  Use assert().  This gets
rid of another use of QERR_UNSUPPORTED.
