    Yes, that I learnt by looking at mounts_open(), the problem is how
    do I get the statctr_pentry (or statctr_group if you like) in
    the open method ? It seems to me that in order to do this, we
    need the following -

    1. An exported wrapper create_statctr_entry() around
    create_seq_entry() code that sticks the statctr_group pointer into
    proc_entry->data.
    2. Some way to get the proc entry from the inode in statctr_open()
    and stick it to seq_file->private for seq_file methods to use.

    Is this understanding correct or is there a better and simpler
    way to do this ?

    Thanks
