(A year, +/- one week, passes...) Since we now have an NFSv4 client/server and it doesn't use VOP_LEASE, and NQNFS is long-gone, I propose we revisit removing VOP_LEASE, which you proposed last year but presumably died as a result of a discussion of whether it might be useful again someday. While not a huge overhead, in practice it means a passage through the VOP vector for every I/O operation, and it certainly adds lines of code. Assuming no objections in the few days, I'll toast VOP_LEASE implementation and calls from the rest of the stack from 8.x so that it's gone before we ship 8.0.
