    Subjectremove_proc_entry behaviour
    Hello linux-kernel,

    I'm writing a patch that uses proc filesystem, and allows creating
    entries in one of /proc subdirectory. They are created by proc_mkdir
    and proc_symlink. But there is a problem when they are to be removed.
    I use remove_proc_entry. They are deleted, but I get the message:

    remove_proc_entry: lease/test busy, count=1
    de_put: deferred delete of test

    I found that first line is generated by the following code in
    remove_proc_entry:

    if (!atomic_read(&de->count))
    free_proc_entry(de);
    else {
    de->deleted = 1;
    printk("remove_proc_entry: %s/%s busy, count=%d\n",
    parent->name, de->name, atomic_read(&de->count));
    }

    The presence of printk suggests that something goes wrong. Is it true?
    What is the proper way of removing proc entry that wouldn't generate
    this message? I get it although I'm sure that entry isn't used by
    anything else...

    nok
