Subject: nvme: introduce nvmet_target_{setup/cleanup} common code
X-Git-Url: https://www.infradead.org/git/?a=commitdiff_plain;h=a12281b8320f67304b8709a081a55560b847770f;p=users%2Fsagi%2Fblktests.git

nvme: introduce nvmet_target_{setup/cleanup} common code

Almost all fabric tests have the identically code for
setting up and cleaning up the target side. Introduce
two new helpers.
