Subject: fadvise: change printing of len argument to unsigned in fadvise64 syscall
X-Git-Tag: v4.14~29

fadvise: change printing of len argument to unsigned in fadvise64 syscall

The kernel declares fadvise64 as
long sys_fadvise64(int fd, loff_t offset, size_t len, int advice);

* fadvise.c (SYS_FUNC(fadvise64)): Change conversion specifier from
"%ld" to "%lu" for printing len argument since kernel expects argument
of type size_t.
