Shatokhin" ------------------- This is a commit scheduled for the next v2.6.34 longterm release. http://git.kernel.org/?p=linux/kernel/git/paulg/longterm-queue-2.6.34.git If you see a problem with using this for longterm, please comment. ------------------- commit a0b8de350be458b33248e48b2174d9af8a4c4798 upstream. We would free the proper number of curves, but in the wrong slots, due to a missing level of indirection through the pdgain_idx table. It's simpler just to try to free all four slots, so do that.
