Starting from the commit0d0443288fthe new function has been introduced which takes struct task_struct as a parameter. Though, compiler doesn't know where to get information about it at this stage. Add missed declaration of struct task_struct to satisfy compiler. Fixes:0d0443288f("string_helpers: add kstrdup_quotable_cmdline") Cc: Kees Cook <keescook@chromium.org> Cc: James Morris <james.l.morris@oracle.com> Signed-off-by: Andy Shevchenko <andriy.shevchenko@linux.intel.com> Acked-by: Kees Cook <keescook@chromium.org>
