Yes, and Izumi Tsutsui committed a change which eliminated the
actual symbols from the kernel, while Christoph Egger committed a
lot of changes which changed the kernel source code to use the
mem*() functions directly instead of indirectly via the b*()
functions.

(I was thinking of a change which would have been a part of what
Izumi committed, but wanted to complete a round of builds with
those changes, but Izumi beat me to it, and did it better.)

For now, the b*() symbols are optionally available to standalone
code (and user-land, of course), but have been evicted from the
kernel.
