Inside init_sa_dir(), reset_sa_dir() is called immediately after dma_pool_alloc() where memset was done for pointer "dir->npe_ctx". Hence removing the memset is fine inside reset_sa_dir() as dma_pool_zalloc() is already doing it. > > Cheers, > -- > Email: Herbert Xu <herbert@xxxxxxxxxxxxxxxxxxx> > Home Page: http://gondor.apana.org.au/~herbert/ > PGP Key: http://gondor.apana.org.au/~herbert/pubkey.txt
