V2 did below changes: [PATCH v2 1/5] generic/139: require 512 bytes to be the minimum dio Improve the code change in _require_odirect() [PATCH v2 2/5] generic/506: call _require_quota before _qmount Nothing changed [PATCH v2 3/5] generic/591: remove redundant output from golden image Replace fflush(stdout) with setlinebuf(stdout). Thanks the review from Dave. [PATCH v2 4/5] generic/591: use proper sector size Remove bad binary files commit, and deal with them in [5/5]. [PATCH v2 5/5] gitignore: ignore missed binary files in src Add two binary files to .gitignore file. Removed original "[PATCH 5/5] generic/623: add overlay into the blacklist", Amir would like to use another patch to deal with it. === Messages from orignal V1 === These 5 patches are random fixes, except patch 4/5 bases on 3/5. - [PATCH 1/5] generic/139: require 512 bytes to be the minimum dio size I tried to help it support 4096 sector size, but it's not simple, especially the golden image broken. So I'm thinking how about limit it in 512 bytes dio testing. - [PATCH 2/5] generic/506: call _require_quota before _qmount As subject - [PATCH 3/5] generic/591: remove redundant output from golden image I think I found where's the issue from, but I'm not sure if it's the best way to fix it. So welcome suggestions :) - [PATCH 4/5] generic/591: use proper sector size Help splice-test to support a sector size option - [PATCH 5/5] generic/623: add overlay into the blacklist I think it's simple to exclude overlay from this test directly, or we have to check if $FSTYP=overlay, then think about how to deal with OVL_BASE_SCRATCH_DEV things.
