Name:We use the pfn of the address for the hash. That way we can check* for freed objects simply by checking the affected bucket.

Proto:static struct debug_bucket *get_bucket(unsigned long addr)

Type:struct debug_bucket

Parameter:

TypeParameterName
unsigned longaddr
472  hash = hash_long((addr >> ODEBUG_CHUNK_SHIFT), ODEBUG_HASH_BITS)
473  Return obj_hash[hash]
