This also changes the open flags from O_RDONLY|O_NONBLOCK|O_DIRECTORY|O_CLOEXEC|O_NOFOLLOW to O_DIRECTORY|O_CLOEXEC. O_RDONLY is redundant, since O_RDONLY is zero anyway, and O_DIRECTORY pins the acces mode enough: it doesn't allow read()/write() anyway when specified. O_NONBLOCK is also pointless given that O_DIRECTORY is specified, it has no meaning on directories. (It is useful if we don't know much about the inode we are opening, and could be a device node or fifo, but the O_DIRECTORY excludes that case.) O_NOFOLLOW is dropped since there's really no point in blocking out the initial entrypoint being a symlink. Once we pinned the the root of the tree it might make sense to restrict symlink use below it, but for the entrypoint itself it doesn't matter.
