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. */
