Miklos, This is a collection of fixes on top of current overlayfs-next. None of the fixes are urgent for -rc1, so up to you. Also wanted to remind you that the top commit of overlayfs-next is missing your s-o-b. Patch 1 is a fix for an oversight from v4.12. Patch 2 is a fix for error handing from v4.7. Patches 3-7 are various fixes to index=on,ro mount. Patches 8-10 are forward compat fixes for when index dir will be used for NFS export. Specifically, patches 9-10 introduce a behavior change in the case of changes to lower layer (rename or delete of lower dir). The new behavior is to verify origin fh and try to decode it if verification fails (overlayfs.txt updated). This change in needed for snapshots and I argue in the commit message of patch 10 why it is needed for indexing of directories. I admit that the argument is not rigorous, but since the behavior of changes to lower layer is documented as "undefined", I recon you don't really mind if we change it for index=on. The rational of making this change in v4.13 as opposed to when directory indexing is implemented, is that index=on already introduces a behavior change related to copying layers, so IMO it is better to introduce all those behavior changes together on index=on. Thanks, Amir.
