Secondly, I've started having problems with it (at least in the
routine that copies from system to user space; the others seem fine).
Specifically, make -j gets a lot of corruption (bogus source files) in
some of the newer kernels that didn't happen even as recently as the
low 1.3.8x's (I only got the usual sig11's that I also got without the
fast copy). This is only an issue with the _tofs routine; if I
disable that one and use the others (_fromfs, "regular" memcpy, and
zero_chunk) everything's fine (although read performance from the
filesystem drops a lot). I'd like someone else to do this to see if
this problem is reproducible or happens only on my system.
