get_bucket

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:

Type	Parameter	Name
unsigned long	addr

472

hash = hash_long((addr >> ODEBUG_CHUNK_SHIFT), ODEBUG_HASH_BITS)

473

Return obj_hash[hash]
