From: Leon Romanovsky <[email protected]>
Use internal kasan header to declare missing prototypes to fix the
following compilation warnings.
mm/kasan/report.c:457:6: warning: no previous prototype for 'report_enabled'
[-Wmissing-prototypes]
457 | bool report_enabled(void)
| ^~~~~~~~~~~~~~
mm/kasan/report.c:482:6: warning: no previous prototype for '__kasan_report'
[-Wmissing-prototypes]
482 | void __kasan_report(unsigned long addr, size_t size, bool is_write,
unsigned long ip)
| ^~~~~~~~~~~~~~
