The `name` parameter in `chdir_notify_entry` was only ever used by chdir_notify_reparent() to produce trace output. That function was removed in5bf546755c(chdir-notify: drop unused `chdir_notify_reparent()`, 2026-06-25), which left `name` with no remaining consumers. Prior to that removal, most callers had already stopped passing a meaningful name, switching to NULL in1f43ff2c7e(refs: unregister reference stores from "chdir_notify", 2026-06-25) and0de2467e6c(odb/source-packed: start converting to a proper `struct odb_source`, 2026-06-17). Since no caller has populated `name` with real data for some time, and its last consumer is gone, drop it from chdir_notify_register(), chdir_notify_unregister(), and the callback signature to simplify the API.
