I'm actually not 100% sure that statement is still correct. What it
meant was that if you compile MMC support into the kernel, you could
not also compile in "pre-emptible kernel threads" support. That is,
system calls would not be pre-emptible if MMC support was in the
kernel. Now that the MMC driver is actually folded into mainline and
not just an added patch, this problem may very well have been resolved.
If you need pre-emptible system calls, then please do just try it, and
see if it works. If it does, then update the wiki :)
