 "verdict": "Not reproducible by construction: dirfs is dead code in this tree (DF-3058 precedent re-verified on this snapshot: no Makefile, absent from sys/conf/files, not loadable, and mount_dirfs refuses non-vkernel platforms). The defect is real in source: dirfs_root performs the dm_root lazy init completely unlocked (VFS_ROOT is not serialized by the VFS layer), so two concurrent path resolutions through the mountpoint both run the init, the loser leaks a dnp + host fd forever and can publish a root vnode without VROOT. Fix authored (serialize with dm_lock); compile validation impossible for dead code.",
