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 ?
