3.16.62-rc1 review patch. If anyone has any objections, please let me know. ------------------ From: Miklos Szeredi <mszeredi@xxxxxxx> commit 580640ba5d331eb5631a5de46941c98f5ed90886 upstream. Use fuse_abort_conn() instead of fuse_conn_kill() in fuse_put_super(). This flushes and aborts requests still on any queues. But since we've already reset fc->connected, those requests would not be useful anyway and would be flushed when the fuse device is closed. Next patches will rely on requests being flushed before the superblock is destroyed. Use fuse_abort_conn() in cuse_process_init_reply() too, since it makes no difference there, and we can get rid of fuse_conn_kill().
