Hi Jenns, We have reports that bcache does not work when CONFIG_DEBUG_FS=n, here is the bug report on bugzilla.kernel.org: https://bugzilla.kernel.org/show_bug.cgi?id=199683 This problem happens since v4.16 and I believe it still happens in v4.17. This submission has one patch to fix this issue, the patch is tested by one of the reporters. If it is not too late for 4.17, could you please to pick it for 4.17-rc6 ? Thanks in advance.
