From: Sagi Grimberg Date: Sun, 29 Mar 2015 12:52:19 +0000 (+0300) Subject: iser-target: Remove conn_ prefix from struct isert_conn members X-Git-Url: http://git.osdn.net/view?a=commitdiff_plain;h=dac6ab305d73b5a67bbb2a0b3d8e2bd6a1383447;p=sagit-ice-cold%2Fkernel_xiaomi_msm8998.git iser-target: Remove conn_ prefix from struct isert_conn members These variables are always accessed via struct isert_conn so no need to have a "conn_" prefix for them.
