From 1d7004f0593f631b78745e4c835d8e09b31f4996 Mon Sep 17 00:00:00 2001 From: Frederico Cadete Date: Sat, 25 May 2013 22:48:57 +0200 Subject: xmem/tmem: fix 'undefined variable' build error. In the (not so useful) kernel configuration where CONFIG_SWAP is undefined and CONFIG_XEN_SELFBALLOONING is defined, xen_tmem_init would use undefined variable 'static bool frontswap'. Added #else to have #define frontswap (0) in the case where CONFIG_FRONTSWAP is not defined.
