Change OK once cleanups are moved to separate patch.

OK


> [PATCH 3/14 linux-2.6.7-rc1] prism54: add iwspy support

Change OK, patch rejected due to Lindent (!!!) being included in this 
patch as well as functional changes.


> [PATCH 4/14 linux-2.6.7-rc1] prism54: add support for avs header in monitor mode

OK


> [PATCH 5/14 linux-2.6.7-rc1] prism54: new prism54 kernel compatibility

rejected, see Arjan's comments

also, prismcompat24.h doesn't belong in the 2.6 kernel.


> [PATCH 6/14 linux-2.6.7-rc1] prism54: Fix prism54.org bugs 74, 75

OK


> [PATCH 7/14 linux-2.6.7-rc1] prism54: Fix 2.4 build

rejected, as per comment for patch #5


> [PATCH 8/14 linux-2.6.7-rc1] prism54: Fix prism54.org bugs 39, 73

cleanups and bug fixes mixed together in same patch.

Change OK once cleanups are moved to separate patch.


> [PATCH 9/14 linux-2.6.7-rc1] prism54: Fix prism54.org bug 77; strengthened oid transaction

More functional changes mixed in with whitespace and formatting cleanups.

Change OK once cleanups are moved to separate patch.


> [PATCH 10/14 linux-2.6.7-rc1] prism54: Don't allow mib reads while unconfigured

Change OK once cleanups are moved to separate patch.


> [PATCH 11/14 linux-2.6.7-rc1] prism54: Touched up kernel compatibility

Rejected due to patch #5 comments.


> [PATCH 12/14 linux-2.6.7-rc1] prism54: Start using likely/unlikely

Use of likely()/unlikely() is OK.

A change to skb_reserve() was snuck into this patch, completely 
unrelated to $subject.  Also, meaningless cleanups obscure things here too.


> [PATCH 13/14 linux-2.6.7-rc1] prism54: Fix 2.4 SMP build

I agree with this change, but this patch also includes unrelated changes!!


> [PATCH 14/14 linux-2.6.7-rc1] prism54: Fix channel stats; bump to 1.2

OK


Summary:  I'm glad you broke up the changes into multiple patches. 
Thank you.  However, the patches were separated in non-sensical ways. 
Follow these guidelines:

1) With this many patches, cosmetic changes (whitespace, formatting, 
Lindent) should be in separate patches from functional changes.

2) Fully describe all the changes in the patch.  If a patch says "fix 
2.4 SMP build", it should do that and nothing else.

3) Kernel compatibility is achieved by coding for the latest kernel 
(2.6.x), and then creating back-compat definitions that make the 2.6.x 
API (as it's used in your driver) work under earlier kernels.  This is 
known as the "kcompat" approach.  See the kcompat toolkit at 
http://sf.net/projects/gkernel/ for examples.

Please resend the patch series with the changes requested.  It is OK if 
you lump Lindent/whitespace/formatting changes into one big patch, if 
you wish -- assuming that patch contains nothing else.
