Hi, I don't know why, but your patch set doesn't apply cleanly against -current= ! so, I merged it in manually. also, take care while importing things to -cur= rent from DFBSD, since DFBSD is a fork from -stable. in other words, your patch = set backout some change done in -current. the following patch set take care of = this. I also tried to reduce the diff against -current whenever possible and made= some style(9) changes (#define<tab> and <space>...<space> to <tab>). thanks anyway and good luck. PS : the following patch set applies and compiles cleanly against -current. however, I didn't have tested it yet since I can't reboot right now.
