[PATCH] splice: add optional input and output offsets
add optional input and output offsets to sys_splice(), for seekable file descriptors: asmlinkage long sys_splice(int fd_in, loff_t __user *off_in, int fd_out, loff_t __user *off_out, size_t len, unsigned int flags); semantics are straightforward: f_pos will be updated with the offset provided by user-space, before the splice transfer is about to begin. Providing a NULL offset pointer means the existing f_pos will be used (and updated in situ). Providing an offset for a pipe results in -ESPIPE. Providing an invalid offset pointer results in -EFAULT.
