Mark those tests as skip when thp is not available. Changes in v2: - replace 'false postive' with 'false negative' in cover letter - patch 1 and patch 2 add reviewed-by/acked-by - new patch 3 to add write_file() in vm_util as a common helper - patch 4 removed the {} in if block, removed the write_file helper rename chunk in v1. Add reviewed-by - patch 5 move the exit chunk to the front of ksft_print_headers() as suggested by David. Add review by.
