34/* The files syswrap-generic.c, syswrap-linux.c, syswrap-*-linux.c,
35   and associated vki*.h header files, constitute Valgrind's model of how a
36   vanilla Linux kernel behaves with respect to syscalls.
37
38   On a few occasions, it is useful to run with a kernel that has some
39   (minor) extensions to the vanilla model, either due to running on a
40   hacked kernel, or using a vanilla kernel which has incorporated a
41   custom kernel module.  Rather than clutter the standard model, all
42   such variant handlers are placed in here.
43
44   Unlike the C files for the standard model, this file should also
45   contain all constants/types needed for said wrappers.  The vki*.h
46   headers should not be polluted with non-vanilla info. */
