Alsa used to kmalloc one file->f_op per file per disconnecting snd_card. This led to oopses sometimes when file->f_op was freed before __fput() finished. Patch adds a virtual device for disconnect: VDD. VDD consists of: LIST_HEAD(shutdown_files) protected by DEFINE_SPINLOCK(shutdown_mutex) static struct file_operations snd_shutdown_f_ops and functions assigned to it Additions to struct snd_monitor_file to specify if instance is hidden by VDD or not. A VDD's instance is created in snd_card_disconnect() under the card->files_lock. cleaned up in snd_card_file_remove() under the card->files_lock.
