After your comments, I'm writing an alternate version that will guarantee a O(N) worst case to both sigkill and cond_resched but frankly this is low priority. Without mmu notifiers /dev/kvm can't be given to a normal luser without at least losing mlock ulimits, so lack of a mmu notifiers is a bigger issue than whatever complexity in mm_lock as far as /dev/kvm ownership is concerned. ------------------------------------------------------------------------- This SF.net email is sponsored by the 2008 JavaOne(SM) Conference Register now and save $200.
