[mpls-linux-devel] Re: Here it comes... big patch for 2.6.1-mpls-1.910 pre series

Re,

What I meant is to do somthing similar to neighbour management, where A.K.
uses a tbl lock and then a per neighbour lock:

"Neighbour hash table buckets are protected with rwlock tbl->lock.
....
   Neighbour entries are protected:
   - with reference count.
   - with rwlock neigh->lock

   Reference count prevents destruction.

   neigh->lock mainly serializes ll address data and its validity state.
   However, the same lock is used to protect another entry fields:
    - timer
    - resolution queue
"


but well, maybe you are right...
