20 actor
21 handler that splices the data
22
24 This function loops over the pipe and calls actor to do the actual
25 moving of a single struct pipe_buffer to the desired destination. It
26 returns when thereĀ“s no more buffers left in the pipe or if the
27 requested number of bytes (sd->total_len) have been copied. It returns
28 a positive number (one) if the pipe needs to be filled with more data,
29 zero if the required number of bytes have been copied and -errno on
30 error.
31
32 This, together with splice_from_pipe_{begin,end,next}, may be used to
33 implement the functionality of __splice_from_pipe when locking is
34 required around copying the pipe buffers to the destination.
