samples/vfs: avoid warning in statx override
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.
Fixes: f1b5618e013a ("vfs: Add a sample program for the new mount API")
