Subject: [PATCH] syscalls: Fix file path names in the header comments

Some of the syscall definitions have moved due to the original source
file being moved into a sub-directory. Update the file path names to
reflect that.

A couple of syscalls such as lookup_dcookie() and nfsservctl() don't
have a syscall definition anymore. Clear the filename and leave the
original subsystem name intact for reference.

Arguably, having filenames in comments might not be the best idea. If the
intention is to make it easier to find a syscall definition, it is probably
faster to just use 'git grep SYSCALL_DEFINE | grep <syscall_name>'. Please let
me know if it would be preferable to just get rid of these comments all
together.

It's probably not worth trying to keep the comments in sync, I'd be in
favor of just removing them all.

Great, thanks! I'll spin up a patch to remove them. You can then choose
to apply either of them.

Subject: [PATCH] syscalls: Remove file path comments from headers

Source file locations for syscall definitions can change over a period
of time. File paths in comments get stale and are hard to maintain long
term. Also, their usefulness is questionable since it would be easier to
locate a syscall definition using the SYSCALL_DEFINEx() macro.

Remove all source file path comments from the syscall headers. Also,
equalize the uneven line spacing (some of which is introduced due to the
deletions).

Great, thanks for the quick response.

While going through the comments, I was wondering if we have a
definition of what constitutes a deprecated syscall vs an obsolete one?

For deprecated we have some information saying:
> /*

> * include/uapi/asm-generic/unistd.h and wanted by >= 1 arch
> */

But, I couldn't find anything for obsolete system calls.

I don't think we've ever defined the two terms properly,
I would assume they are used interchangeably here. If we wanted
a definition, 'obsolete' could mean syscalls that are no longer
used by current software while 'deprecated' are those that
are still called by glibc and others on the architectures that
provide them but are emulated through modern variants on other
architectures. Without any documentation on the topic, or a
definite list, other interpretations are equally possible.
