ed 7d2bdda0cd Remove D_NEEDGIANT from io(4). ... There is no need to mark this device node to use Giant. The only architectures that use io(4) (i386 and amd64) only change a flag in td->td_frame, which is only accessed by curthread. Apart from this change, I think some fishy things may happen when using /dev/io in multithreaded applications. I haven't tested, but looking at the code, the flag doesn't get cleared when close() is called from another thread, but this may not be this important. I'm not removing D_NEEDGIANT from mem(4), because this driver isn't Giant safe at all (it calls GIANT_REQUIRED).		2008-08-08 13:43:56 +00:00
