Modified Files:
        src/sys/ufs/ufs: ufs_inode.c

Log Message:
Break hold-and-wait which happens in ufs_balloc_range() when we
have pages busied and are trying to get the genfs node lock.
This causes a lock order reversal described in PR kern/40389.
This is not a proper fix and only a workaround for NetBSD 5.0.
