Headers placed in include/linux/ form part of the kernel's internal API and signal to subsystem maintainers that other parts of the kernel may depend on them. By moving lockd.h into fs/lockd/, lockd becomes a more self-contained module whose internal interfaces are clearly distinguished from its public contract with the rest of the kernel. This relocation addresses a long-standing XXX comment in the header itself that acknowledged the file's misplacement. Future changes to lockd internals can now proceed with confidence that external consumers are not inadvertently coupled to implementation details.
