From: Sagi Grimberg Date: Tue, 14 Apr 2015 15:08:14 +0000 (+0300) Subject: IB/iser: Remove redundant cmd_data_len calculation X-Git-Tag: firefly_0821_release~176^2~1881^2^3~14 X-Git-Url: http://demsky.eecs.uci.edu/git/?a=commitdiff_plain;h=ecc3993a2ad2a4ce8f1a58a08e9177f21015492d;p=firefly-linux-kernel-4.4.55.git IB/iser: Remove redundant cmd_data_len calculation This code was added before we had protection data length calculation (in iser_send_command), so we needed to calc the sg data length from the sg itself. This is not needed anymore. This patch does not change any functionality.
