The information you are passing from the nfs server to the lease code is largely ignored by the lease code and is passed back to the nfs server, in the sm_breaker_owns_lease call back. If try_break_deleg() passed the 'delegated_inode' pointer though to __break_lease(), it could pass it through any_leases_conflict() and leases_conflict() to the lm_breaker_owns_lease() callback. Then container_of() could be used to access whatever other data nfsd had stashed near the inode. The common code wouldn't need to know any of the details. Just a thought... NeilBrown
