        aufs: bugfix, valid ptr in radix tree instead of dummy 1

        When a process whose pid is larger than 32768 (default),
        si_pid_set_slow() crashes due to a dummy value.
        Replace the value by a valid pointer.

        aufs: bugfix, O_CLOEXEC for the plink maintenance mode

        /sbin/mount.aufs (and others) puts aufs into the plink maintenance mode
        via /proc/fs/aufs/plink_maint which make many other operations to return
        error or block.
        During in this mode, /sbin/mount.aufs exec(2) the original mount(8).
        If mount(8) is not statically linked, it may mmap(2) ld.so (and
        others). And if ld.so is inside of the target aufs, then aufs mmap(2)
        blocks, ie. deadlock.
        To address this problem, specify O_CLOEXEC for /proc/fs/aufs/plink_maint
        which makes aufs to exit the plink maintenance mode, and ->release()
        doesn't care about pid.
