    [PATCH] Add support for the sys_vmsplice syscall · 912d35f8
    Jens Axboe authored
    sys_splice() moves data to/from pipes with a file input/output. sys_vmsplice()
    moves data to a pipe, with the input being a user address range instead.
    
    This uses an approach suggested by Linus, where we can hold partial ranges
    inside the pages[] map. Hopefully this will be useful for network
    receive support as well.
