 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.
