lockd: Remove dead code from fs/lockd/xdr.c

2026-06-09T20:32:59+00:00

All NLMv3 server-side procedures now dispatch through xdrgen-generated encoder and decoder functions, leaving the hand-written XDR processing in fs/lockd/xdr.c with no remaining callers. Remove fs/lockd/xdr.c, the fs/lockd/svcxdr.h header it included, the Makefile entry, and the now-unused nlmsvc_decode_* / nlmsvc_encode_* prototypes from fs/lockd/xdr.h. The structure definitions and status code macros in xdr.h are retained as they are still used by the client-side code. Reviewed-by: Jeff Layton Signed-off-by: Chuck Lever

lockd: Rename struct nlm_reboot to lockd_reboot

2026-06-09T20:32:59+00:00

As part of the effort to enable lockd's server-side XDR functions to be generated from the NLM protocol specification (using xdrgen), the internal type names must be changed to avoid conflicts with the machine-generated type names. Rename struct nlm_reboot to struct lockd_reboot for consistency with the other renamed internal types. Reviewed-by: Jeff Layton Signed-off-by: Chuck Lever

lockd: Rename struct nlm_res to lockd_res

2026-06-09T20:32:59+00:00

As part of the effort to enable lockd's server-side XDR functions to be generated from the NLM protocol specification (using xdrgen), the internal type names must be changed to avoid conflicts with the machine-generated type names. Rename struct nlm_res to struct lockd_res to avoid conflicts with the NLMv3 XDR type definitions that will be introduced when svcproc.c is converted to use xdrgen.

lockd: Rename struct nlm_lock to lockd_lock

2026-06-09T20:32:59+00:00

A subsequent patch will convert fs/lockd/svcproc.c to use machine-generated XDR encoding and decoding functions in a manner similar to fs/lockd/svc4proc.c. Machine-generated types derived from the NLM specification will conflict with the internal types of the same name. Rename the internal struct nlm_lock type to lockd_lock to avoid such naming conflicts. Reviewed-by: Jeff Layton Signed-off-by: Chuck Lever

lockd: Add LOCKD_SHARE_SVID constant for DOS sharing mode

2026-03-30T01:25:09+00:00

Replace the magic value ~(u32)0 with a named constant. This value is used as a synthetic svid when looking up lockowners for DOS share operations, which have no real process ID associated with them. Reviewed-by: Jeff Layton Signed-off-by: Chuck Lever

lockd: Relocate include/linux/lockd/lockd.h

2026-03-30T01:25:09+00:00

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. Reviewed-by: Jeff Layton Signed-off-by: Chuck Lever

lockd: adapt to breakup of struct file_lock

2024-02-05T12:11:43+00:00

Most of the existing APIs have remained the same, but subsystems that access file_lock fields directly need to reach into struct file_lock_core now.

SUNRPC: Change return value type of .pc_encode

2021-10-13T15:34:49+00:00

Returning an undecorated integer is an age-old trope, but it's not clear (even to previous experts in this code) that the only valid return values are 1 and 0. These functions do not return a negative errno, rpc_stat value, or a positive length. Document there are only two valid return values by having .pc_encode return only true or false.

SUNRPC: Replace the "__be32 *p" parameter to .pc_encode

2021-10-13T15:34:49+00:00

The passed-in value of the "__be32 *p" parameter is now unused in every server-side XDR encoder, and can be removed. Note also that there is a line in each encoder that sets up a local pointer to a struct xdr_stream. Passing that pointer from the dispatcher instead saves one line per encoder function.
