This snipit from isert_put_cmd() looks interesting:
...
/*
* Check for special case during comp_err where
* WRITE_PENDING has been handed off from core,
* but requires an extra target_put_sess_cmd()
* before transport_generic_free_cmd() below.
*/
if (comp_err &&
cmd->se_cmd.t_state == TRANSPORT_WRITE_PENDING) {
struct se_cmd *se_cmd = &cmd->se_cmd;
target_put_sess_cmd(se_cmd);
}
...
