[PATCH v1 06/36] lockd: Relocate include/linux/lockd/lockd.h

[Chuck Lever <cel@kernel.org>]

From: Chuck Lever <chuck.lever@oracle.com>

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.
