Bruce has a pending patchset that will enable delegations in the Kernel NFSD server. He has introduced a new delegation object at the lock-manager, and so on. We at user mode would like to acquire such delegations and be notified of their revocation, synchronously so we can recall them form clients before new access is granted. Again perhaps this API can be united with the new locks API we want. fctl or syscall ? Thanks Boaz
