From f1db320ec5788d5fcc05c0285bd0980319185497 Mon Sep 17 00:00:00 2001 From: Wei Liu Date: Thu, 16 May 2013 23:24:28 +0000 Subject: [PATCH] xen-netback: remove dead code The array mmap_pages is never touched in the initialization function. This is remnant of mapping mechanism, which does not exist upstream. In current upstream code this array only tracks usage of pages inside netback. Those pages are allocated when contructing a SKB and passed directly to network subsystem. Signed-off-by: Wei Liu Acked-by: Ian Campbell Signed-off-by: David S.
