Note that you cannot necessarily link to every file in the filesystem even with a 4k block size, since the absolute path to a file can be over PATH_MAX. PATH_MAX is a limit on the path string passed to syscalls, not a limit on the directory structure. By using cwd-relative paths, fd-relative paths, chroots, or bind mounts, you can create a directory structure that is much deeper than PATH_MAX. None of the major Linux filesystems enforce a directory depth limit, as far as I know -- and even if one did, it could still be mounted at a mountpoint whose absolute path is already PATH_MAX, or close to it. -- You are receiving this mail because: You are watching the assignee of the bug.
