2020-07-09samples/vfs: avoid warning in statx overrideKees Cook
[ Upstream commit c3eeaae9fd736b7f2afbda8d3cbb1cbae06decf3 ] Something changed recently to uncover this warning: samples/vfs/test-statx.c:24:15: warning: `struct foo' declared inside parameter list will not be visible outside of this definition or declaration 24 | #define statx foo | ^~~ Which is due the use of "struct statx" (here, "struct foo") in a function prototype argument list before it has been defined: int # 56 "/usr/include/x86_64-linux-gnu/bits/statx-generic.h" foo # 56 "/usr/include/x86_64-linux-gnu/bits/statx-generic.h" 3 4 (int __dirfd, const char *__restrict __path, int __flags, unsigned int __mask, struct # 57 "/usr/include/x86_64-linux-gnu/bits/statx-generic.h" foo # 57 "/usr/include/x86_64-linux-gnu/bits/statx-generic.h" 3 4 *__restrict __buf) __attribute__ ((__nothrow__ , __leaf__)) __attribute__ ((__nonnull__ (2, 5))); Add explicit struct before #include to avoid warning.

2019-03-20vfs: Add a sample program for the new mount APIDavid Howells
Add a sample program to demonstrate fsopen/fsmount/move_mount to mount something. To make it compile on all arches, irrespective of whether or not syscall numbers are assigned, define the syscall number to -1 if it isn't to cause the kernel to return -ENOSYS.
