unknown field 'swap_slot_free_notify' specified in initializer #66

Closed GoogleCodeExporter closed 9 years ago

GoogleCodeExporter commented 9 years ago 
What steps will reproduce the problem?
1. Patched kernel with patch_swap_notifier_generic_2.6.25.diff (all others
did not patch correctly)
2. Compiled kernel
2. Downloaded compcache-0.6.2.tar.gz 
3. Uncommented #define CONFIG_SWAP_FREE_NOTIFY
4. Set compile vars:

export
CCOMPILER=/media/Android_dev/Donut_AOSP/prebuilt/linux-x86/toolchain/arm-eabi-4.
4.0/bin/arm-eabi-
KERNEL_BUILD_PATH=/media/Android_dev/Kernel/linux-new/

5. Attempting to compile compcache modules
make ARCH=arm CROSS_COMPILE=$CCOMPILER KERNEL_BUILD_PATH=$KERNEL_BUILD_PATH

RESULT:

make -C /media/Android_dev/Kernel/linux-new/
M=/media/Android_dev/Kernel/compcache-0.6.2 modules

What version of the product are you using? On what operating system?
DSTL1
Android 1.6
2.6.28 kernel

Please provide any additional information below.

Compiles fine if I don't do Step #3

Should I use compcache-0.5.4?

compcache-0.5.4 works fine...

Any way to get or mod one of the 0.6.2 patches for my kernel?

Sorry, jumped the gun... it does not compile with either version

0.5.4 errors:

So what does this tell me?

notify patch modifications don't want to compile against kernel... why? No 
idea. Help
appreciated.

I will checkout kernel 2.6.28 and check the problem.

Yes, it is.

You seem to be again using the same failing patch as mentioned in initial bug 
report. I uploaded a new test version (see comment 8) - please try that one. 
Please also mention kernel version you are using now.

Looks like your kernel does not have LZO de/compressor compiled as built-in or 
as modules. For this, select 'Crytographic API -> LZO compression algorithm' 
during menuconfig phase.

Apparently the swap notify patch breaks my Wi-Fi & BT, any ideas?

I don't have slightest of idea. BTW, whats BT?

BT -> bluetooth probably

Yea, I'm lost...
Everything is cool until I patch it.
The NOTIFY patch allows for a faster cleaning of compressed cache in RAM.
So how much performance loss am I to suffer without this patch?
I still have to even try the compcache feature.

Without notify patch, you might waste a lot of memory due to stale data. 

Anyways, I simply can't see how this patch can affect WiFi!

It seems that adding swap_slot_free_notify to struct block_device_operations 
break the version check. The prebuilt modules I am using must be keeping an old 
define of struct block_device_operations.

Is there an way around this?
