Only used in one place, should be static instead of adding it in a .h
Same for the other ones.
$ git grep xor_altivec_2
[...]
arch/powerpc/lib/xor_vmx_glue.c:EXPORT_SYMBOL(xor_altivec_2);
Are you sure I can change this function to static ?
Yes you are right. But in fact those fonctions are already defined in
asm/xor. h
So you just need to add the missing #include
I originally tried it, but this leads to:
CC arch/powerpc/lib/xor_vmx_glue.o
In file included from arch/powerpc/lib/xor_vmx_glue.c:16:0:
./arch/powerpc/include/asm/xor.h:39:15: error: variable
‘xor_block_altivec’ has initializer but incomplete type
static struct xor_block_template xor_block_altivec = {
^~~~~~~~~~~~~~~~~~
./arch/powerpc/include/asm/xor.h:40:2: error: unknown field ‘name’
specified in initializer
.name = "altivec",
^
[...]
The file <asm/xor.h> (powerpc) is pretty much expected to be included
after <include/linux/raid/xor.h>.
I did not want to tweak <asm/xor.h> to test for #ifdef _XOR_H just before
#ifdef _XOR_H
static struct xor_block_template xor_block_altivec = {
[...]
since this seems like a hack to me.
Is this ok to test for #ifdef _XOR_H in <arch/powerpc/include/asm/xor.h> ?
What about including linux/raid/xor.h in asm/xor.h ?
Or better: including linux/raid/xor.h then asm/xor.h in xor_vmx_glue.c ?
