ntb: ntb_perf missing dmaengine_unmap_put
In the normal I/O execution path, ntb_perf is missing a call to dmaengine_unmap_put() after submission. That causes us to leak unmap objects. Signed-off-by: Dave Jiang <dave.jiang@intel.com> Fixes: 8a7b6a77 ("ntb: ntb perf tool") Signed-off-by: Jon Mason <jdmason@kudzu.us>
