Wow, nice!

modpost really does want all the modules at once, so it can check for
unresolved symbols.  So xargs is out, we need to implement stdin-reading
directly.

Bikeshedding on the option name reveals no established standard:
-S/--stdin-file-list in shar, -T/--files-from=i in tar, --files-from=-
in rsync.

Now, if someone can find a better way of getting the module list into a
file/stdin, I'm all ears.  I'm not sure the find works in all cases...

Thanks,
Rusty.

That's what I thought.  A better approach would be to delete a few
thousand drivers ;)

I worry that we'll also explode some internal limit in make(1) when
preparing that list.  We'll see.

Could just read the filenames from stdin if none were provided on the
command line, but whatever.

How is that list generated at present?

So we have a vast string within make(1) and need to get it into a temp
file without using shell commands?  Tricky.

I guess that's OK, as long as modpost handles non-object files
gracefully.

What's the risk that the find stumbles across random .ko files from
last month?  Pretty small, I guess - a `make clean' appears to rubs out
all .o files, even for different architectures.

That'll screw up if the file doesn't end in \n?

make is used in some pretty unweildy projects, so I'd be surprised if we
hit that.

That wouldn't be very unixy...

Actually, this patch is *crap*.  modpost is what generates the .ko
files: we need the .o file equivalents.  The find command wouldn't work
on a clean tree...

But that's OK, we actually generate the module list above, so we can
reuse that same logic.

In a break-compile way, yes.  But fixed...

If this passes review, I'll split properly into three patches.

Thanks,
Rusty.

modpost: handle huge numbers of modules.

(FIXME: Split into multiple patches).
