Btrfs: avoid buffer overrun in btrfs_printk The buffer read-overrun would be triggered by a printk format starting with <N>, where N is a single digit. NUL-terminate after strncpy. Use memcpy, not strncpy, since we know the string we're copying fits in the destination buffer and contains no NUL byte. Signed-off-by: Jim Meyering <meyering@redhat.com>
