The pnfs tree base of of 2.6.29-rc5 uses the new find_last_bit
function (defined in
lib/find_last_bit.c) in a file in the fs/nfs directory.  Myself and
another developer (though no one else so far) get the following error
during compile:

   Kernel: arch/x86/boot/bzImage is ready  (#5)
     Building modules, stage 2.
     MODPOST 515 modules
   ERROR: "find_last_bit" [fs/nfs/nfs.ko] undefined!
   make[2]: *** [__modpost] Error 1
   make[1]: *** [modules] Error 2
   make: *** [sub-make] Error 2


Note that find_last_bit() is not used in any file in the fs directory.
If I add it to any function that is EXPORT_SYMBOL'ed
from the fs directory, suddenly the compile errors go away.  (See the
below patch for a more concrete example.)

I am not sure what is going on, and why it only affects some
developers, but it looks a lot like the kbuild system
is deciding that the library does not need to be included at the fs
directory level, so isn't including it in fs/nfs where
it is needed.

Thanks for any help.
Fred

Subject: [PATCH 1/1] DEBUG: Need this to compile - what the heck?

This looks suspiciously like a bug in the kbuild system, where
the library include is not passed down to fs/nfs unless it is
used by fs.  Without this, I get the following error during linking:

Kernel: arch/x86/boot/bzImage is ready  (#5)
 Building modules, stage 2.
 MODPOST 515 modules
ERROR: "find_last_bit" [fs/nfs/nfs.ko] undefined!

Where is the pnfs tree?

A failing .config file would be helpful.

Is CONFIG_GENERIC_FIND_LAST_BIT set in your .config file?

If you change lib/Makefile like this:
-lib-$(CONFIG_GENERIC_FIND_LAST_BIT) += find_last_bit.o
+obj-$(CONFIG_GENERIC_FIND_LAST_BIT) += find_last_bit.o

i.e., s/lib/obj/, does your build succeed?

Yes, it does work with that change.

kbuild only links in libaries if there is any users of siad library.
And your normal config has no users of lib/find_last_bit.c so
it is not linked into the kernel.

The general rule is that if any in tree module uses a library
then the library is always linked in.
And to always link in a library you need to patch the Makefile
as Randy suggest in his mail.

I don't understand your comment.  There *is* a user of the library in the
(modified) fs/nfs/nfs4proc.c.  The problem is that it doesn't compile unless
there is also a user in some fs/*.c.

Again, I suspect I am misunderstanding.  It seems you are suggesting
that to compile the nfs code I have to alter lib/Makefile.  While that is a
useful workaround, that is certainly not a viable solution.

If you build nfs (or pnfs) into the kernel image instead of as a
loadable module, does the build succeed?  I expect that it does
(or would).

Why not?  We do that same change for other library options.

There need to be an in-kernel user and I expect fs/nfs/nfs4proc.c is
build as a module.

Yes, you are correct.

I was working under the assumption that, in order to compile nfs, I should
only have to adjust the fs/nfs/Makefile.  You seem to be saying that when
we submit upstream a patch that uses find_last_bit(), if there are no other
in-kernel users at that time, we will have to submit a patch to lib/Makefile,
similar to commit 5a6dca7... lib: move bitmap.o from lib-y to obj-y.
If that is what you mean, I can live with that.

Thanks for your help.
