    [PATCH] Introduce sys_splice() system call · 5274f052

    This adds support for the sys_splice system call. Using a pipe as a
    transport, it can connect to files or sockets (latter as output only).
    
    From the splice.c comments:
    
       "splice": joining two ropes together by interweaving their strands.
    
       This is the "extended pipe" functionality, where a pipe is used as
       an arbitrary in-memory buffer. Think of a pipe as a small kernel
       buffer that you can use to transfer data from one end to the other.
    
       The traditional unix read/write is extended with a "splice()" operation
       that transfers data buffers to or from a pipe buffer.
    
       Named by Larry McVoy, original implementation from Linus, extended by
       Jens to support splicing to files and fixing the initial implementation
       bugs.
