[Xen-devel] [Patch] Trivial fix for compile failure with latest glibc

["Stephen C. Tweedie" <sct@xxxxxxxxxx>]

Hi,

libxc fails to compile for me on the very latest glibc due to a
combination of -Werror, a switch() statement in xc_ptrace() without a
default, and 4 new enum values in the latest glibc.  Easy fix attached.

Fix libxc compile failure against new glibc

libxc's ptrace code #includes <sys/ptrace.h> for enum __ptrace_request,
and in xc_ptrace() has a long switch statement to handle the various
cases.  Unfortunately the latest glibc adds various new values to the
enum which are not caught in the switch statement, and so compilation
with -Werror fails.

Fix this the trivial way with a default: so that both older and newer
glibcs still work.
