Subject: [PATCH 03/11] target: Inline transport_put_cmd()
Date: Tue, 31 Oct 2017 18:03:11 +0000 [thread overview]
Message-ID: <20171031180319.19258-4-bart.vanassche@wdc.com> (raw)
Since all transput_put_cmd() does is to call target_put_sess_cmd(),
inline transport_put_cmd() into its callers. Leave out the BUG_ON()
statement because if cmd->se_tfo = NULL then cmd->cmd_kref is 0
and kref_put() will complain anyway. Notes:
- transport_init_se_cmd() initializes both .se_tfo and .cmd_kref.
- The only target driver that does not call transport_init_se_cmd()
for all commands is the iSCSI target driver. See also
iscsi_target_rx_opcode().
