[PATCH v3 2/4 -mmotm] copy_signal() cleanup: killtaskstats_tgid_init() and acct_init_pacct()

From: Veaceslav Falico
Date: Tue Dec 15 2009 - 05:20:48 EST


Kill unused functions taskstats_tgid_init() and acct_init_pacct() because we
don't use them anywhere after using kmem_cache_zalloc() in copy_signal().
