Okkk Thank you so much for reply... If it is not by default functionality in quota, then I want add a reset function in source code of quota without deleting a data of user. Can you help me in this...
I explained you several times that this can't work as it is against the fundamentals a quota system is made for and I showed you an alternative approach, I don't want to repeat myself. If you want to modify the Linux quota kernel module instead, then you might better post on the Linux kernel mailinglist.
