This is due to the commented out VOP_ABORTOP (I have no idea why this is commented out, it just always has been). >How-To-Repeat: vmstat -m # note the memory use of namei cd <some writable nfs-mounted filesystem> ln /kernel foo # should fail with cross-dev link vmstat -m # see namei grow, grow namei grow >Fix: Stick in "FREE(cnp->cn_pnbuf, M_NAMEI)" >Audit-Trail: >Unformatted:
