Step back a minute and think about how you create a sysctl entry. It's with a call to register_sysctl_table(), right? And what is the parameter of that function? It takes a table that describes the sysctl directory structure. And from that you can see the different quota sysctl entries and variables. Look at the sys_table and fs_table structures for that information, understand how they work and then you will be able to find any sysctl entry in the kernel source quite easily. hope this helps, greg k-h _______________________________________________ Kernelnewbies mailing list Kernelnewbies@xxxxxxxxxxxxxxxxx https://lists.kernelnewbies.org/mailman/listinfo/kernelnewbies
