[PATCH 0/10] [compat-2.6 and compat-stable] Mostly build fixes

[Hauke Mehrtens]

This patch series is for compat-2.6 and compat-stable-2.6.32. I have
compiled compat-wireless against mainline kernel 2.6.25 to 2.6.32. This
was all done with Ubuntu 9.04. compat-wireless should still compile with
openSuse, but I have not tried it.

The compat-stable fixes are addressing some compile problems with older
kernel versions. I have not tested all supported kernels.

The last stable kernel was added later so the number does not match.

[PATCH 1/9] [compat-2.6 and compat-stable] Export round_jiffies_up again.

[Hauke Mehrtens]

The 2.6.27 mainline kernel does not export round_jiffies_up. It looks
like the openSuse kernel 2.6.27 does export this symbol. Rename the
compat symbol to not conflict with the openSuse kernel.

Did you then mean to rename the above to backport_round_jiffies_up then?

because otherwise then we have here the define so existing
wireless-testing code maps to the backport_round_jiffies_up(), and the
declaration of round_jiffies_up() also gets preprocessed as
backport_round_jiffies_up() -- the only thing missing would be the
compat exported symbol but I saw that didn't change.

Come to think of it -- because of the define you added the
compat-2.6.28 code *will* rename the code to add the backport_ prefix
so that is why this compiles. I'll leave it like that. Thanks.

LINUX_VERSION_CODE >= KERNEL_VERSION(2,6,28) can not be true in

Hmm, I am not questioning your decision for removing unused code, but
if they are genuinely unused, why were they introduced in the first
place?

As a side comment, while it is unusual (compared to the usual <
version_X), it is a possible scenario for compat-X.h to have codes
that conditions on LINUX_VERSION_CODE >= version_X - and if memory
serves the bits you are removing were added only recently; and they
looks like what they are (i.e. public kernel symbols became
private-static during 2.6.27<->2.6.28 or the other way round).

I guess I am looking for a reason why they were added in the first
place, if they serve no purpose.

I have added them in edcf845e4bd65d00132f02237bee3fd3daca318f but I can
not find any references to them in compat-wireless. For me it looks like
it was a mistake to introduce them. The commit comment does not say
anything about it (my bad) and I forgot why I added it.

The condition #if (LINUX_VERSION_CODE >= KERNEL_VERSION(2,6,28)) was
added recently because without it openSuse with kernel 2.6.27 will not
compile. OpenSuse backports the tracepoint part into their 2.6.27 kernel.

I remember that thread now. It is probably wrong as a matter of policy
to incorporate patches for distro kernels with backport bits through.
- I am not saying you shouldn't be helpful and provide them - after
all, more users == better testing, and no doubt the investigation
itself throws more insights on the detailed mechanisms - but it is
just that compat-wireless probably should not try to support arbitrary
and substantial changes from a vanilla kernel. I know Suse is popular
so it is important to support Suse users, but I am wondering if
distro-specific changes should be separate or at least, clearly
documented.

Not sure why opensuse added round_jiffies_up() to their 2.6.27
kernels, greg may know better, but since its only once change I'm
willing to live with what we did to resolve for it.

We added that to the SLE 11 kernel as it was requred for a bunch of
block layer backports to resolve a number of issues that we needed to
do.

Hope this helps explain things,

I guess for older releases where we copied over the iw_handler.h we
were then sending the kernel the wrong data for these callers. We
could just try to propagate the iw_handler changes to
compat-wireless-stable. This would probably fix a few unreported
issues.
