-Increase ``io.DEFAULT_BUFFER_SIZE`` from 8k to 128k. Adjust :func:`open` on
-Linux to use ``max(io.DEFAULT_BUFFER_SIZE, device block size)`` rather than
-the device block size. Improve I/O write performance by up to 5 times.
+Increase ``io.DEFAULT_BUFFER_SIZE`` from 8k to 128k and adjust :func:`open` on
+platforms where ``fstat`` provides a ``st_blksize`` field (such as Linux) to use
+``max(io.DEFAULT_BUFFER_SIZE, device block size)`` rather than always using the
+device block size. This should improve I/O performance.
