    Ah, okay. I thought this modpost.c change would be enough to accomplish
    that, but I didn't look too closely:

    @@ -1721,8 +1721,10 @@ static void add_header(struct buffer *b, struct
    module *mod)
    void add_staging_flag(struct buffer *b, const char *name)
    static const char *staging_dir = "drivers/staging";
    + static const char *fsstaging_dir = "fs/staging";

    - if (strncmp(staging_dir, name, strlen(staging_dir)) == 0)
    + if (strncmp(staging_dir, name, strlen(staging_dir)) == 0 ||
    + strncmp(fsstaging_dir, name, strlen(fsstaging_dir)) == 0)
    buf_printf(b, "\nMODULE_INFO(staging, \"Y\");\n");

    Are the core changes onerous? If you don't object in principle, it would
    be nice if staging file systems were easier to find.
