Actually, the block with error can be safely removed from kern_poll.c before we polish our patches. There is no problem running SMP + polling. Probably, there were some problems in the past. I think the block can be removed now and MFCed before 5.4-RELEASE. I'm quite sure that our patches for Giant-less polling will not be MFCed soon. -- Totus tuus, Glebius. GLEBIUS-RIPN GLEB-RIPE
