Indeed. I missed RDTUN flag. > module unload is broken:( Maybe it can be fixed at a (bit) later date? I don't think Gleb will be happy with this. Some time ago he removed some vimage related stuff to prevent crashing on module unload (see r229849). Actually your patch looks like a partial revert of that commit. So I think you need to think about this issue from start. At least it should not crash non-vimage kernel and there should be understanding how to fix it for vimage kernel. Your approach with keeping only one purge thread might make it simpler. -- Mikolaj Golub _______________________________________________ email@example.com mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-virtualization To unsubscribe, send any mail to "freebsd-virtualization-unsubscr...@freebsd.org"
