Subject: [PATCH] zram: zcomp_strm remove ambiguous description
Date: Mon, 7 Jun 2021 09:08:20 -0700 [thread overview]
Message-ID: <1623082100-22086-1-git-send-email-yongw.pur@gmail.com> (raw)
From: wangyong <wang.yong12@zte.com.cn>
buffer element in the structure is only used for compression.
buffer element is not used in decompression.
So "/* compression/decompression buffer */" is a little ambiguous.
buffer is used in the following two places:
1.__zram_bvec_write: src = zstrm->buffer
2.zcomp_compress: crypto_comp_compress(zstrm->tfm,
src, PAGE_SIZE,
zstrm->buffer, dst_len);
