Nit: Most of blktests filess keep each line within 80 characters.
     Folding the line above into two lines is a bit better for small
     terminals.

	echo "wwnn=${wwnn},wwpn=${wwpn},marginal=${marginal}" \
		> ${loopctl}/set_marginal_rport

Nit: it can be a bit shorter:

	if [[ "${nvme_trtype}" != "fc" ]]; then
