From: Ingo Molnar Date: Mon, 13 Oct 2008 06:51:38 +0000 (-0700) Subject: net/mac80211/rx.c: fix build error X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=bf94e17bc8d35fc339945a42990a2f2b5e9b5a40;p=GitHub%2FLineageOS%2FG12%2Fandroid_kernel_amlogic_linux-4.9.git net/mac80211/rx.c: fix build error older versions of gcc do not recognize that ieee80211_rx_h_mesh_fwding() is unused when CONFIG_MAC80211_MESH is disabled: net/built-in.o: In function `ieee80211_rx_h_mesh_fwding': rx.c:(.text+0xd89af): undefined reference to `mpp_path_lookup' rx.c:(.text+0xd89c6): undefined reference to `mpp_path_add' as this code construct: if (ieee80211_vif_is_mesh(&sdata->vif)) CALL_RXH(ieee80211_rx_h_mesh_fwding); still causes ieee80211_rx_h_mesh_fwding() to be linked in. Protect these places with an #ifdef. commit b0dee578 ("Fix modpost failure when rx handlers are not inlined.") solved part of this problem - this patch is still needed.
