[PATCH 0/18] Convert sendfile to splice

Hi, This series of splice patches removes file_operations ->sendfile() from the kernel and converts do_sendfile() to use ->splice_read() to achieve the same function. -- Jens Axboe - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [EMAIL PROT

[PATCH 1/18] splice: abstract out actor data

For direct splicing (or private splicing), the output may not be a file. So abstract out the handling into a specified actor function and put the data in the splice_desc structure earlier, so we can build on top of that. This is the first step in better splice handling for drivers, and also for im
