Subject: [PATCH bpf-next 2/2] tools, bpftool: Define attach_type_name array only once
Date: Mon, 22 Jun 2020 16:00:07 +0200	[thread overview]
Message-ID: <20200622140007.4922-3-tklauser@distanz.ch> (raw)
In-Reply-To: <20200622140007.4922-1-tklauser@distanz.ch>

Follow the same approach as for map_type_name and prog_type_name. This
leads to a slight decrease in the binary size of bpftool.

Before:

   text	   data	    bss	    dec	    hex	filename
 399024	  11168	1573160	1983352	 1e4378	bpftool

After:

   text	   data	    bss	    dec	    hex	filename
 398256	  10880	1573160	1982296	 1e3f58	bpftool
