Subject: [PATCH 1/1] inet: Eliminate dead store in 'iproute_default_modify'.
Date: Thu, 14 Dec 2023 16:58:19 -0800	[thread overview]
Message-ID: <20231215005820.2141277-1-gerickson@nuovations.com> (raw)

In 'iproute_default_modify' there is a dead store to
'rth.req.u.r.rt.rtm_scope' with 'RT_SCOPE_NOWHERE' only to be
overwritten two lines later with 'RT_SCOPE_UNIVERSE' without an
intervening read.

This eliminates the dead store of 'RT_SCOPE_NOWHERE'.
