kref_put

函数名称：kref_put - decrement refcount for object.*@kref: object.*@release: pointer to the function that will clean up the object when the* last reference to the object is released.* This pointer is required, and it is not acceptable to pass kfree

函数原型：static inline int kref_put(struct kref *kref, void (*release)(struct kref *kref))

返回类型：int

relay_destroy_buf	lay_destroy_buf - destroy an rchan_buf struct and associated buffer*@buf: the buffer struct
relay_close_buf	lay_close_buf - close a channel buffer@buf: channel buffer Marks the buffer finalized and restores the default callbacks.* The channel buffer and channel buffer data structure are then freed* automatically when the last reference is given up.
relay_open	lay_open - create a new relay channel@base_filename: base name of files to create, %NULL for buffering only@parent: dentry of parent directory, %NULL for root directory or buffer@subbuf_size: size of sub-buffers@n_subbufs: number of sub-buffers*@cb:
relay_close	lay_close - close the channel@chan: the channel Closes all channel buffers and frees the channel.
relay_file_release	lay_file_release - release file op for relay files@inode: the inode@filp: the file* Decrements the channel refcount, as the filesystem is* no longer using it.
