Hmm... from what I see, data structure user_beancounter is _not_ defined for a single resource, it is a beancounter for _all_ resources. struct user_beancounter { atomic_t ub_refcount; spinlock_t ub_lock; uid_t ub_uid; struct hlist_node hash; struct user_beancounter *parent; void *private_data; /* resources statistics and settings */ struct ubparm ub_parms[UB_RESOURCES]; }; ub_parms of _all_ controllers are held in this data structure. So, keeping the beancounter data structure inside _a_ controller specific data structure doesn't sound right to me, as other controllers might also have the same need ?! Controller _owns_ only ub_parms[controller_id], not the whole user_beancounter, right ? -- ---------------------------------------------------------------------- Chandra Seetharaman | Be careful what you choose.... - [EMAIL PROTECTED] | .......you may get it. ---------------------------------------------------------------------- ------------------------------------------------------------------------- Using Tomcat but need to do more?
