Subject: [Qemu-devel] [PATCH] linux-user: Fix compilation when F_SETPIPE_SZ isn't defined
Date: Thu, 30 Jun 2016 17:33:49 +0100	[thread overview]
Message-ID: <1467304429-21470-1-git-send-email-peter.maydell@linaro.org> (raw)

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.
