Remove BUG_ON if p_arglen=0 to allow RPC with void arg.
Remove BUG_ON if p_replen=0 to allow RPC with void return.
The former was needed for the first revision of the LOCALIO protocol
which had an RPC that took a void arg:
/* raw RFC 9562 UUID */
typedef u8 uuid_t<UUID_SIZE>;
program NFS_LOCALIO_PROGRAM {
version LOCALIO_V1 {
void
NULL(void) = 0;
uuid_t
GETUUID(void) = 1;
} = 1;
} = 400122;
The latter is needed for the final revision of the LOCALIO protocol
which has a UUID_IS_LOCAL RPC which returns a void:
/* raw RFC 9562 UUID */
typedef u8 uuid_t<UUID_SIZE>;
program NFS_LOCALIO_PROGRAM {
version LOCALIO_V1 {
void
NULL(void) = 0;
void
UUID_IS_LOCAL(uuid_t) = 1;
} = 1;
} = 400122;
There is really no value in triggering a BUG_ON in response to either
of these previously unsupported conditions.
NeilBrown would like the entire 'if (proc->p_proc != 0)' branch
removed (not just the one BUG_ON that must be removed for LOCALIO's
immediate needs of returning void).

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the reStructuredText markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
