From: Ian Campbell Date: Mon, 16 May 2011 23:59:48 +0000 (+0000) Subject: xen: netback: use __CONST_RING_SIZE not __RING_SIZE X-Git-Tag: 2.1b_release~4192^2~50 X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=11e73de7ccc1c9c61c65f914a214cb6467966a51;p=platform%2Fkernel%2Fkernel-mfld-blackbay.git xen: netback: use __CONST_RING_SIZE not __RING_SIZE The later causes warnings with gcc 4.5+. __CONST_RING_SIZE was introduced in 667c78afaec0 to fix this but as netback wasn't upstream at the time it did not benefit, hence: CC drivers/net/xen-netback/netback.o drivers/net/xen-netback/netback.c:110:37: warning: variably modified 'grant_copy_op' at file scope [enabled by default] drivers/net/xen-netback/netback.c:111:30: warning: variably modified 'meta' at file scope [enabled by default] drivers/net/xen-netback/netback.c: In function 'xen_netbk_rx_action': drivers/net/xen-netback/netback.c:584:6: warning: variable 'irq' set but not used [-Wunused-but-set-variable] Thanks to Witold Baryluk for pointing this out.
