linux-next: cifs tree build failure

[-- Attachment #1: Type: text/plain, Size: 570 bytes --]

Hi Steve,

Today's linux-next build (powerpc ppc64_defconfig) failed like this:

fs/cifs/connect.c: In function 'cifs_mount':
fs/cifs/connect.c:2545: error: 'struct cifs_sb_info' has no member named 'mountdata'

Caused by commit da9e1ebdf6fc4630329afcad11855113ad6023b6 ("Remote DFS
root support").  I will use the cifs tree form next-20090402 (which
really just drops that one commit).

Presumably CONFIG_CIFS_DFS_UPCALL is not defined in my config.

Jeff,
I just applied and reviewed your patch 5 (thus modified your patch
slightly before merging).

My fault. That function gets introduced in a later patch and I had a
bogus call left in here from when I reorganized the series. This
patch should fix it and a typo that got silently fixed in a patch that
hasn't been committed yet.

This patch should fix both. Steve F., let me know if you want me to
respin the series on top of this patch. Note that there's still a
harmless compiler warning that gets fixed in a later patch in the
series.

An even better fix (as far as I am concerned) would be for you to pull
the net tree into the cifs tree (since the net tree will *never* rebase,
this is safe) and then apply the following two fixups as part of the
merge.  Or if you want to rebase the cifs tree, then use a merge of
Linus' tree and the net tree as the base and fix up the relevent commits
with the following.

That way, I don't have to carry these fixups ...  I have had to reapply
the fist once already as things continue to change.

Actually, from my perspective, killing the macros turns out to
be a good thing.  It caught a potential revert of the conversion
we did in CIFS already, for example :)

Unlike a compile failure, we don't have some automated thing
scanning new patches looking for references to turds like these
NIPQUAD macros which we want to remove.

Looks good to me too -- I don't think we have any more changes in the
CIFS ipv6 address formatting code coming too soon...

Still, is there some reason that NIP6/NIPQUAD stuff needs to be removed
at the same time as we add %pI4/%pI6? An period where the old NIP*
defines still live in the tree seems like a reasonable thing.

fs/cifs/cifsfs.c:364: error: implicit declaration of function 'NIP6'

Caused by the interaction of commits
b189db5d299c6824780af5590564ff608adb3dea ("net: remove NIP6(), NIP6_FMT,
NIP6_SEQFMT and final users") from the net tree and
20c4eef4f817ff65337e2fb3f1f5df52eeca09eb ("cifs: display addr and
prefixpath options in /proc/mounts") from the cifs tree.

I have reverted the include/linux/kernel.h part of the net tree patch for
now since the replacement (%p6) is not upstream yet ...

Dave, can you apply the below to the net tree, please.  The old interface
should really not go away until at least the end of the next merge
window ...
