Revert "mm: add /proc controls for pdflush threads"
This reverts commit fafd688e4c0c34da0f3de909881117d374e4c7af.
Work is progressing to switch away from pdflush as the process backing
for flushing out dirty data. So it seems pointless to add more knobs
to control pdflush threads. The original author of the patch did not
have any specific use cases for adding the knobs, so we can easily
revert this before 2.6.30 to avoid having to maintain this API
forever.
