Most of the bits just need a bit of refinement I think, instead of being forced through the overlayfs tree and are generally fine. The pre_mmap hook I think is a clear no-go. We've had this tried multiple times and always rejected it. Unlike previous uses the overlayfs use isn't outright broken, but still questionalable as it will still lead to a copyup that "leaks" if the actual mmap wasn't successfull. The whole discussion of how mmap happens, how we deal with mmap_sem and failures needs a broader discussion with all MM and VFS folks first. -- To unsubscribe from this list: send the line "unsubscribe linux-unionfs" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
