Not really an expert on bcache, and not that much in blktests either, but having some testing for bcache readabily available is fantastic! > Note: to run this tests blktests TEST_CASE_DEV_ARRAY needs to be set: > > # cat config > TEST_CASE_DEV_ARRAY[bcache/*]="/dev/nvme0n1 /dev/vdb /dev/vdc" Can you add a blurb to Documentation/running-tests.md about this? I also wonder if we could have a generic TEST_CASE_DEV_ARRAY that would just work for all tests needing multiple devices?
