proc: remove pathetic ->deleted WARN_ON
WARN_ON(de && de->deleted); is sooo unreliable. Why? proc_lookup remove_proc_entry =========== ================= lock_kernel(); spin_lock(&proc_subdir_lock); [find proc entry] spin_unlock(&proc_subdir_lock); spin_lock(&proc_subdir_lock); [find proc entry] proc_get_inode ============== WARN_ON(de && de->deleted); ... if (!atomic_read(&de->count)) free_proc_entry(de); else de->deleted = 1; So, if you have some strange oops [1], and doesn't see this WARN_ON it means nothing. [1] try_module_get() of module which doesn't exist, two lines below should suffice, or not?
