From ddf31aa853a32925f8141dbcb66fdc84f999ece1 Mon Sep 17 00:00:00 2001 From: Peter Maydell Date: Thu, 30 Jun 2016 17:33:49 +0100 Subject: [PATCH] linux-user: Fix compilation when F_SETPIPE_SZ isn't defined Older kernels don't have F_SETPIPE_SZ and F_GETPIPE_SZ (in particular RHEL6's system headers don't define these). Add ifdefs so that we can gracefully fall back to not supporting those guest ioctls rather than failing to build.
