There are a lot of patches trying to match various [kv].alloc allocations to specific frees.
But are there frees in a fast path?
Why not convert kfree to add a few extra tests
and add #defines for existing uses
Something like:
void kfree(const void *addr)
{
if (is_kernel_rodata((unsigned long)addr))
return;
if (is_vmalloc_addr(addr))
_vfree(addr);
else
_kfree(addr);
}
And add defines like:
#define kvfree kfree
#define vfree kfree
#define kfree_const kfree
Does 4 extra tests really matter?
