I don't find any issue. a few nit are below.

.TP 10
.I arena
The total amount of memory allocated by means other than
.BR mmap (2)
(i.e., memory allocated on the heap).
This figure includes both in-use blocks and blocks on the free list.
.TP
.I ordblks
The number of ordinary (i.e., non-fastbin) free blocks.
.TP
.I smblks
The number of fastbin free blocks (see
.BR mallopt (3)).

It would be nice if a meaning of fastbin was described here.
It is allocation cache (for increasing cpu cache hit ratio) from
point of bird view.

.TP
.I hblks
The number of blocks currently allocated using
.BR mmap (2).

It would be nice if glibc malloc try to allocate memory by using mmap directly
if size is greater than MMAP_THRESHOLD.

Also nice if refer mallopt and MMAP_THRESHOLD.
