    vfs: remove LOOKUP_NO_AUTOMOUNT flag · b6c8069d

    That flag no longer makes sense, since we don't look up automount points
    as eagerly any more.  Additionally, it turns out that the NO_AUTOMOUNT
    handling was buggy to begin with: it would avoid automounting even for
    cases where we really *needed* to do the automount handling, and could
    return ENOENT for autofs entries that hadn't been instantiated yet.
    With our new non-eager automount semantics, one discussion has been
    about adding a AT_AUTOMOUNT flag to vfs_fstatat (and thus the
    newfstatat() and fstatat64() system calls), but it's probably not worth
    it: you can always force at least directory automounting by simply
    adding the final '/' to the filename, which works for *all* of the stat
    family system calls, old and new.
    So AT_NO_AUTOMOUNT (and thus LOOKUP_NO_AUTOMOUNT) really were just a
    result of our bad default behavior.
